Explanation: An article can't be consistent with everything, so choices must be made, and Wikipedia's choice is to value the intelligibility gained by consistency between a given article and external literature on the same topic, more than it values the intelligibility gained by consistency between that article and other articles on other topics. |

No. 10 Downing Street and so on
Right now we've got
- Proper names, technical terms, and the like are never altered: 5 Channel Street; Channel 5; Chanel No. 5; Fourth Judicial District; Fourth Amendment; Fourth Estate; Fourth Republic
-- and that's fine. But what about certain conventional situations that aren't proper names e.g.
- Along the south side of X street are No. 123, where Historical Personage died, and No. 137, where Infamous Killer lured his victims.
-- ? In English usage, at least, reference to Number. 123 or No. 123 are conventional -- do we require the text to say Number 123 every time, or is No. 123 OK here?
In older American usage you see that some time, but nowadays (it is my impression) it's more common to write "at 123 was This, and at nearby 137 was That."
Anyway... thoughts on writing "No. 123"? EEng (talk) 10:13, 29 June 2014 (UTC) Bump EEng (talk) 04:08, 5 July 2014 (UTC)
What's happened to all the MOS warriors?
has the fire gone out? Can't I get a peep re the above? EEng (talk) 18:11, 11 July 2014 (UTC)
- I don't know if this will be much help, but as a Briton, I can tell you what I do myself. I personally use the numero sign, as in № 10 Downing Street. I do speak the "number" allowed. I personally would advocate for using the numero sign, as opposed to "number", which is never written out as far as I know. However, I wouldn't be surprised if the American usage of "123 Such and Such Road" started seeping in, and I've certainly heard "10 Downing Street" being used occasionally on BBC News reports in recent years, whereas they would've previously said "№ 10". RGloucester — ☎ 22:16, 11 July 2014 (UTC)
- If "No." is the common usage, I'd say keep it unaltered. For a Canadian example (though not related to a street), Leduc No. 1. Resolute 22:48, 11 July 2014 (UTC)
- If it's the world according to MOS you seek, your answer is here: MOS:NUMBERSIGN. Oddly, it's not found or referenced on the "Manual of Style/Dates and Numbers," but on the first page of "Wikipedia:Manual of Style." I edit a lot of sports articles and the number abbreviation rules come up a lot as many sports fans want to insert the number sign symbol (#) directly into text, which is a no-no. I had to go looking for the specific MOS section, and was a little surprised to find it elsewhere than on the MOS numbers subpage. Cheers. Dirtlawyer1 (talk) 23:45, 11 July 2014 (UTC)
- I was aware of NUMBERSIGN though I couldn't remember where it was. Leduc No. 1 is covered under the proper names rule. I guess what I was wondering was whether the flat prohibition on No. might be relaxed in this situation where convention strongly endorses it i.e. "house numbers", such as in the examples above, for times and places where that was the convention. The weird thing is I had an actual article situation when I posed the question, but I can't even remember what it is now! I don't know... I do think this usage should be allowed. Anyone want to propose text? EEng (talk) 02:55, 23 July 2014 (UTC)
...gives the example "Humans diverged from apes long ago, but only recently developed fire." One plausible theory is that cooking developed first, then homo erectus and eventually humans. See Catching Fire: How Cooking Made Us Human. There must be a better analogy. Aymatth2 (talk) 01:36, 19 July 2014 (UTC)

Fractions vs decimals in imperial units
Many moons ago I wrote articles converting cm to inches with fractions - such as in Banksia ericifolia - and felt more comfortable doing this. Somewhere along the way I passively and not unhappily went along with using decimals of inches, such as in current FAC Epacris impressa. Someone else has stated they prefer the fractions. I can't see anything in MOS or MOS archives about this...has this been discussed before and do we have a consensus? Cas Liber (talk · contribs) 08:44, 23 July 2014 (UTC)
- The "moons" is not a MOS-conpliant chronological unit, so you'll need to repost before we can start arguing about this.
- For years, a strict reading of MOSNUM did not allow any standard time measurement longer than a day, so think yourself lucky. Kahastok talk 21:55, 23 July 2014 (UTC)
- The "moons" is not a MOS-conpliant chronological unit, so you'll need to repost before we can start arguing about this.
- I don't have information on that, but have some observations. Banksia ericifolia has:
- 9–20 mm (⅓–¾ in)
- MOS:FRAC says to use {{frac}}:
- 9–20 mm (1⁄3–3⁄4 in)
- Ideally {{convert}} should be used so future editors don't have to wonder if the conversions are correct or have been changed. However, convert can only handle one value of fraction in the output, although it will reduce the fraction if appropriate:
{{convert|9-20|mm|abbr=on}}
→ 9–20 mm (0.35–0.79 in) (this line is to show the values){{convert|9-20|mm|abbr=on|frac=4}}
→ 9–20 mm (1⁄4–3⁄4 in){{convert|9-20|mm|abbr=on|frac=8}}
→ 9–20 mm (3⁄8–3⁄4 in)
- A problem with fractions is that they are pretty crude as far as conveying information regarding precision, although for this context precision is not appropriate. I find going from 1⁄3 to 3⁄4 to require too much mental effort—it's hard to compare the values. Johnuniq (talk) 11:01, 23 July 2014 (UTC)
![](https://upload.wikimedia.org/wikipedia/commons/thumb/1/11/Angry_mob_of_four.jpg/130px-Angry_mob_of_four.jpg)
- The benefit of fractions with imperial units is that the units themselves are not decimally-based, so the subdivisions are very often give awkward decimals. 4.1 feet is not a nice number of inches. 5.2 pounds is not a convenient number of ounces. But in those situations the best solution is to use the subdivision explicitly (e.g. 4 ft 2 in).
- As to divisions of units like inches, ounces, that don't have a standard subdivisions, fractions are probably more traditional and decimals may look wrong to some - but may be clearer to others. Personally, I don't have a strong preference either way. Kahastok talk 21:55, 23 July 2014 (UTC)
- If you read WP:UNIT, you'll see that mixed units are preferred for the imperial system. Fractions should be used, as the system is not a decimal system. Mixed units, like "5ft 2in", should be preferred. In instances where there is no commonly used smaller unit, like with the ounce, use fractions. Imperial units don't make sense, frankly, when put into decimals. That's not how they were meant to be used. RGloucester — ☎ 22:00, 23 July 2014 (UTC)
- I'm not sure about all cases of this question, but if the inches (as in the example) are a parenthetical conversion from a measurement given in the source in decimal (obviously) millimeters, then I think the inches should be in decimal as well. I certainly see decimal inches in some engineering contexts (though sometimes they're obviously modernizations of fractions, as e.g. a 1.125-inch bolt) and for the scientific context of the OP that seems right too. But I don't have this clearly thought out. EEng (talk) 22:13, 23 July 2014 (UTC)
Are we using : or * for each comment? It started out as colons.
Some readers like imperial measurements and these readers nearly always think fractions are quite natural. Other readers prefer metric measurements and these readers nearly always prefer decimals. I don't come across many people who like imperial measurements with decimals and I don't come across many people who like metric measurements with fractions. Also, when we use a measurement on WP we should make it agree with the source reference. Some fractions like 9+1/2 can easily be converted to a decimal like 9.5 but some like 9+1/3 either lose precision by converting to a shortened decimal like 9.3 or gain unwarranted precision as 9.3333333333333 (typically measured with a tool that is accurate to only a few decimal places). Luckily we {{convert}}
which is happy to deal with imperial fractions and decimal metric units. Readers who have trouble with imperial fractions can just ignore them and look at the decimal metric units. Similarly, readers who never quite made the transition to metric can ignore the metric units and just read the familiar imperial fractions. Both sides are happy and can ignore the other side.

Kilowatt-hour
- This is prompted by a discussion at Template talk:Convert#Kilowatt-hour.
{{convert}} provides two units for kilowatt-hour; one is for "common usage", while the other outputs the correct middle dot per WP:UNIT. Examples:
{{convert|123|kWh|abbr=on}}
→ 123 kWh (440 MJ){{convert|123|kW.h|abbr=on}}
→ 123 kW⋅h (440 MJ)
Kilowatt hour asserts 'The symbol "kWh" is most commonly used in commercial, educational, scientific and media publications
'—including "scientific" might be overdoing it, but the others are correct in my experience. Given that kWh is commonly used, what should be the output from convert? Should the above example using kWh give the same output as kW.h? Or should it be up to the editor to decide which to use?
The only discussion I can find is at 2008 MOSNUM. In May 2014 there were 61 converts using kWh in 36 articles, and none using kW.h. I prefer that convert gives the editor the choice of how the output should appear, and I support the principle that Wikipedia should follow real life rather than lead it. However, if a strong consensus wants the middle dot, that's fine too. Johnuniq (talk) 07:32, 29 July 2014 (UTC)
I have just noticed that several energy units have been carefully designed to allow the editor to either insert a middot or not.
- No middot: µWh mWh Wh kWh MWh GWh TWh
- With middot: µW.h mW.h W.h kW.h MW.h GW.h TW.h
I wonder if Jimp would like to explain the history. Johnuniq (talk) 08:15, 29 July 2014 (UTC)
- Just to echo here my arguments from the preceding discussion: consistency (among units and with standards) is more important; the claim about "real-life" usage has not been supported by studies.
And, in fact, my point was that conversion to kilowatt-hours ({{convert|123|MJ|abbr=on}}
) should produce "kW·h" instead of "kWh". — Mikhail Ryazanov (talk) 07:57, 29 July 2014 (UTC)- Re
{{convert|123|MJ|abbr=on}}
: That's just a matter of specifying the output unit (|kW.h
), or changing the default output unit for MJ and friends. Johnuniq (talk) 08:15, 29 July 2014 (UTC)- The default output should be according to MOS (with "·"). I doubt that the dot-less output is needed (that is, I think that both "xWh" and "xW.h" parameters should produce "xW·h"). — Mikhail Ryazanov (talk) 08:28, 29 July 2014 (UTC)
- Re
- Another thought is that some people actually misunderstand "kWh" as "kilowatt per hour" (similarly to "psi", which is "pound per square inch"), whereas with "kW·h" the meaning is clear. — Mikhail Ryazanov (talk) 08:09, 29 July 2014 (UTC)
- Those people do not even know what the dot means.
-- [[User:Edokter]] {{talk}}
08:38, 29 July 2014 (UTC)
- Those people do not even know what the dot means.
- kWh is by far the most common usage (even in scientific papers), so it should remain the default. The concatenated unit has the same meaning as the dotted unit anyway; they both represent a factored unit.
-- [[User:Edokter]] {{talk}}
08:38, 29 July 2014 (UTC)- No! For example, "m·s" means "meter-second", but "ms" means "millisecond". Please read WP:UNITS, the standards and the previous discussions. — Mikhail Ryazanov (talk) 09:58, 29 July 2014 (UTC)
- "ms" is not a concatenation but a prefix.
-- [[User:Edokter]] {{talk}}
10:47, 29 July 2014 (UTC)- Both kW h and kW·h are correct symbols for kilowatt hour. By contrast, kWh, while sometimes used as an abbreviation, is not a correct symbol. MOSNUM should promulgate correct use (kW h or kW·h). Dondervogel 2 (talk) 10:52, 29 July 2014 (UTC)
- "ms" is not a concatenation but a prefix.
- No! For example, "m·s" means "meter-second", but "ms" means "millisecond". Please read WP:UNITS, the standards and the previous discussions. — Mikhail Ryazanov (talk) 09:58, 29 July 2014 (UTC)
- Statements such as "KWh is not a correct symbol" misunderstand what we're doing here. kWh is not a formal scientific symbol, but like it or not it's the long-established convention, in authoritative sources, for topics such as e.g. Electric energy consumption, and articles on those topics should (even must) follow that usage. Thus convert and other templates must offer kWh as an option, along with the other two -- purists who happen to be tinkering with the template must not impose their views on what should be, instead of what is (in reliable sources, that is). EEng (talk) 15:12, 29 July 2014 (UTC) P.S. Wikipedia does not "promulgate" any usage, correct or incorrect; it strives to reflect the usage of reliable sources, giving preference to the best sources in any given topic area.
- I did not mention Wikipedia. Only MOSNUM. Surely the purpose of MOSNUM is to promulgate a uniform practice throughout Wikipedia? If not that, what else? Dondervogel 2 (talk) 15:27, 29 July 2014 (UTC)
- I misunderstood you -- thought you meant WP "promulgating" to the wider world, as in trying to set a good example of ideal usage. I see now you mean MOS setting an example/giving guidance to WP editors. Yes, that's what MOS is for, but again, what MOS promulgates is what's used in reliable sources, and that varies from field to field. So, as mentioned, while in a physics papers you'd see kW{{middot}h or kW h, in a discussion of consumer energy conservation you'd see kWh. EEng (talk) 18:25, 29 July 2014 (UTC)
- I have also seen KWH used on utility bills. I'm not sure I have ever seen any extra characters added. Vegaswikian (talk) 18:48, 29 July 2014 (UTC)
- "KWH" in bills is probably a dark legacy of ancient printers that did not have any glyphs except numbers ans capital letters. :–) — Mikhail Ryazanov (talk) 23:53, 29 July 2014 (UTC)

- Above it is asserted that many scientific publications use kWh. I can't say I read any scientific publications devoted to electric power generation and distribution. However, the IEEE has several publications devoted to this area including IEEE Transactions on Power Apparatus and Systems, IEEE Transactions on Power Delivery, and IEEE Transactions on Power Systems. The IEEE provides "Preparation of Papers for IEEE TRANSACTIONS and JOURNALS" (April 2013). That publication on page 2 states "Use the center dot to separate compound units, e.g., 'A·m2.'" I suggest this indicates that one of the largest scientific publishers in this field has chosen middle dots, therefore, if WP:MOS does the same, it is not pushing a novel or marginally accepted practice. I would like to see WP:MOS continue to recommend the choices recognized in official standards, that is, the middle dot or the space. Of course, articles should follow WP:MOS except when WP:IAR applies. I take the comment by Dondervogel 2 at 15:27, 29 July 2014 (UTC) to mean that Wikipedia articles should not contain statements that widely used language is incorrect, but that does not mean that Wikipedia articles should use such language if it does not conform to the language used in the best sources. Jc3s5h (talk) 16:50, 29 July 2014 (UTC)
- You're wasting your time arguing whether kWh is or isn't used in scientific papers. It clearly is in sources such as discussions of consumer energy consumption, national energy policy, etc., and articles on those topics will therefore use it. Speaking of IEEE, here for example is IEEE's own "Smart Grid Forum" [1] -- a bit bloggish, but still clearly IEEE-sponsored (and IEEE is very careful about its publishing standards) using -- ta ha! -- kWh with no dot and not space. You're focused on standards for the highest-level, most formal journals, and that isn't appropriate for all articles.
- If the question on the table is, What should the convert template to, the answer is that it must off dot, space, and no-dot-no-space as output options. If the question is, what should articles use, I think we should leave that to editors of individual articles. If and when it appears that there's a recurring issue that wastes editors' time, that would be the time to think about adding something to MOS. EEng (talk) 18:25, 29 July 2014 (UTC)
- The piece cited by EEng as an example fails. Doug Houseman or his copy editor can't even get the capitalization of units and symbols right. Jc3s5h (talk) 19:53, 29 July 2014 (UTC)
- It seems to me that the question is whether MOSNUM should promulgate good practice or common practice. In my opinion it is good practice that should prevail. I see a clear parallel with Mbps vs Mbit/s, where the latter is recommended by MOSNUM because it is the internationally agreed symbol, and therefore unambiguous. The same logic applies here. Dondervogel 2 (talk) 20:08, 29 July 2014 (UTC)
- That's not a very good parallel because there is no division in kWh. No-one who understands basic algebra would insert a division there would they? I've never seen it with a centre dot here in the UK. Even the article that we cite in our Kilowatt hour article as evidence of confusion uses kWh without a dot or space. Dbfirs 20:44, 29 July 2014 (UTC)
- There are many instances of less-than-ideal usage which are not bad enough to create confusion, such as irregardless or "I could care less." That's no reason to encourage such less-than-ideal usage. There is also the danger that someone who is familiar with the meaning of "kWh" but not familiar with some other compound unit symbol may use "kWh" as an exemplar to decide how to (incorrectly) construct the symbol for the other unit. Jc3s5h (talk) 21:06, 29 July 2014 (UTC)
Crikey, will you get a clue? OK, tell me that the Lawrence Berkeley Lab is sloppy and unreliable as well [2] This is as hopeless a quest as were earlier attempts to get mpg in articles about automobiles changed to miles/gallon. Forget it. You're wasting everyone's time. EEng (talk) 22:03, 29 July 2014 (UTC)
- I can tell you that people at LBNL are not better than in other places, and thus it is not surprising that the draft that you refer to is not something to rely upon (besides "kWh", it is typographically disgusting in many respects). — Mikhail Ryazanov (talk) 23:41, 29 July 2014 (UTC)
- You're wasting yours and everyone else's time EEng (talk) 03:28, 30 July 2014 (UTC)
- Well, "psi" and "scfm" have an invisible division in them. :–) As I pointed above, the kilowatt-hour article even mentions the "kilowatt per hour" confusion explicitly, so this problem is not so illusory. — Mikhail Ryazanov (talk) 10:50 pm, Today (UTC−4)
- You're wasting yours and everyone else's time EEng (talk) 03:28, 30 July 2014 (UTC)
"kWh" is the only way I have ever seen it in the electric utility industry or in news articles. The pattern is the same with Wh, MWh, GWh, and TWh, not to mention similar units like kVA and MVA. I am unable to recall the last time I have seen "kW h" or "kW·h" in a utility industry communication or in a news article; I suspect that I may never have seen the units written that way, in many thousands of occurrences. Call it original research if you like, but you would be hard-pressed to show even a tiny minority of sources using anything other than "kWh". Offering the dotted option in the convert template is a kindness to pedantic editors and wikiprojects that dictate a specific style for units, but widespread use of the dotted option on Wikipedia would be contrary to the vast majority of real-world usage. – Jonesey95 (talk) 03:36, 30 July 2014 (UTC)
- Agree with Jonesey above, with most of my work in energy-related projects, "kWh" is near universal, and even "kW-hr" will have wider usage than "kW(dot)h". Our article on the unit of "kilowatt-hours" can explain the proper units, but for any other case, we should be using the most recognized units. --MASEM (t) 03:52, 30 July 2014 (UTC)
- Please keep in mind that "communications or news articles" are oriented on plain-text typesetting, and they used to be authored on regular typewriters that simply lacked the interpunct symbol. For the same reason there are no equations, for example. Here we don't have such technical limitations, so why not to follow the standards? Especially, since this would be totally free: just type
{{convert|...}}
and get the perfect results! — Mikhail Ryazanov (talk) 04:34, 30 July 2014 (UTC)- You're not listening. Different topic areas use different symbols. One of them is kWh. Stop wasting everyone's time. EEng (talk) 04:48, 30 July 2014 (UTC)

Regarding the history of why when the unit was added to {{convert}} the option of the dotless abbreviation was given, I don't completely remember the specifics (it was almost seven years ago) but this must have been before MOSNUM had anything to say about it and given that "kWh" is so common I guess including it must just have made sense. If I were adding the unit to the template now, though, I'd probably comply with MOSNUM and wouldn't give the dotless option. So, do we fix the template or the guideline? My preference would be for uniformity as opposed to making an ad hoc exception for watt-hours. There are plenty of abbreviations in use out there that we don't allow. If we were to take an anything-goes approach, why have a MOS at all? Jimp 14:18, 30 July 2014 (UTC)
- By including kWh as an option we are complying with MOS, because what MOS says is Unit names and symbols should follow the practice of reliable sources, and as abundantly demonstrated above, in some subject areas RSs use kWh. I point out that MOS' guidance "Indicate a product of unit symbols with & middot; or & nbsp;" is part of a table headed "General guidelines", not "Rigid restrictions". So far this debate has gone on at the convert template's talk page, and here on MOS, but -- tellingly -- AFAIK not in the context of any actual articles. This is a solution in search of a problem. In fact, to put an end to this I make the following proposal:
- Regardless of the niche usages of the "kWh" notation, conversion from MJ to kW·h implies that the main units in the particular article are the SI units, so the result of the conversion should also be formatted according to the SI rules. — Mikhail Ryazanov (talk) 10:33 pm, Today (UTC−4)
- This is ridiculous. If -- as is obvious from the below will happen -- kWh is endorsed as an option (along with kW h and kW·h), then the output of convert will need to offer kWh as an option (along with kW h and kW·h) for its output. You're trying to use the machinery of convert as a back-door way to force people to insert a space or dot in kWh (at least when they use convert). WP:STICK EEng (talk) 03:37, 1 August 2014 (UTC)

Proposal
- Add to WP:Manual_of_Style/Dates_and_numbers#Specific_units, in the Energy section, a new row as follows: kilowatt-hour ... kWh / MWh / GWh ... Where reliable sources in a given subject area (such as energy supply and consumption) do so, the symbols kWh, MWh, GWh (with no space) are used in place of (for example) the formal kW h (i.e. with space) or kW·h.
- Support. EEng (talk) 16:43, 30 July 2014 (UTC)
- Support, suggest to also add MWh and GWh (but no others) as common usage when you start talking power plants. Other magnitudes of "watt hours" typically are otherwise not used frequently enough to require this. (I rearely see TWh used, usually that gets spelled out better, for example) --MASEM (t) 16:58, 30 July 2014 (UTC)
- Added MWh and GWh to the proposal. I left it intentionally ambiguous as to Wh since, really, it's use in RS that controls, so just let editors figure that out if it comes up somewhere. EEng (talk) 17:12, 30 July 2014 (UTC)
- I guess I wanted to make sure it was clear it was only to their specific decimations of the Watt-hour unit. I could see someone trying to argue mWr (milliwatt-hr) as the "right" unit display, though at that magnitude, the units typically switch over to joules. The three listed as explicitly the only prefix-ified versions of "watt-hour" that would be acceptable due to their common usage). --MASEM (t) 00:03, 31 July 2014 (UTC)
- So you're OK with the wording? EEng (talk) 00:26, 31 July 2014 (UTC)

- Oppose because the proper symbol will not confuse those familiar with the proper way of writing metric units, but the incorrect symbol may very well confuse those who are just learning to write metric symbols correctly.
Also "kW-h" is wrong.Jc3s5h (talk) 17:01, 30 July 2014 (UTC), sentence struck in response to change in proposal at 18:30 UT.
- It's not wrong. It's not consistent with how other units typically are written, no question, but its an artifact of how the energy/power industry worldwide use the symbols. --MASEM (t) 17:09, 30 July 2014 (UTC)
- Oops. Fixed hyphen to middot. Jc's reasoning would be an argument for changing mpg to miles per gallon in articles on cars, and converting all articles to American English. Wikipedia follows reliable sources in whatever subject area is being treated. EEng (talk) 17:12, 30 July 2014 (UTC)
Oppose, for the same reason as Jc3s5h, and because in the absence of a good reason not to, it makes sense for MOSNUM to follow international standards. Precisely the same reasoning as for nmi (nautical mile), kn (knot) and bit/s (bit per second). If you follow widespread use why doesn't MOSNUM advocate use of nm, kt and bps for those units. I am not aware of an internationally agreed symbol for mpg, which makes it a poor counter-example. Dondervogel 2 (talk) 18:12, 30 July 2014 (UTC)
- I can't speak for knots and so on, but the reason bps is a no-no is that its a well-known source of confusion because of its bits-bytes ambiguity. Your fetishizing of "international standards" is a red herring. We follow the sources in each topic area, not "international standards" (unless that's what the sources follow).
- Tell you what. Why don't you go change all the uses of kWh at Electricity meter, Emission standard, Energy density , Cost of electricity by source , Feed-in tariff , Financial incentives for photovoltaics , Feed-in tariffs in Germany , Energy in the United States , Solar power, Solar power in Massachusetts and see the reaction. Then come back and let us know. EEng (talk) 18:51, 30 July 2014 (UTC)
- I did do that once. For kilotonnes (kt) and nanometers (nm) I mean. Before I learnt of the existence of mosnum, I changed them one by one to knots (kn) and nautical miles (nmi). I encountered lots of resistance of the kind you anticipate, from editors who preferred kilotonnes and nanometres. International standards are sources in their own right, of a kind, and the most reliable sources follow them. When I discovered mosnum I found an easier way. Make a good case here, and others will follow. Dondervogel 2 (talk) 20:14, 30 July 2014 (UTC)
- You did that once for some other units, but not for kWh. You can't keep saying that "the most reliable" sources use certain terms when we've clearly shown that there are perfectly good sources that use a different term. Here are more: [3] [4] [5] [6] [7] Now go start a discussion at Cost of electricity by source -- see what kind of laugh you get. EEng (talk) 20:45, 30 July 2014 (UTC)
- The place to make the case is not in individual articles, but here in mosnum. And that is what I am doing. I agree that use of kW h is rare (which just means that reliable sources are rare), but I see no advantage in departing from a perfectly simple multiplication rule that is easy to explain and easy to understand. Use of the correct symbol would also make it easier to understand that kW h is a product of kilowatt and hour. Dondervogel 2 (talk) 21:40, 30 July 2014 (UTC)
- Now you're showing that you really have the wrong end of the stick. Ultimately these decisions are made on a case-by-case basis in articles -- that's why MOS is a guideline. And we don't add a new "rule" to MOS unless it's clear that editors in individual articles are wasting time rehashing the same old issues. What's being proposed here isn't a rule but an "anti-rule", reaffirming, specifically in the case of kilowatt-hours, that editors of each article should follow the notation of RS in that topic area.

- Oppose. If you really want to use the non-standard notation, at least change the wording from the prescriptive "are used in place of" to a permissive "can be used". — Mikhail Ryazanov (talk) 03:38, 31 July 2014 (UTC)
- You're still confused. The standard notation is whatever is standard in the topic area a given article treats -- you want one particular source to be the "standard" for everything. What the proposal says is
- Where reliable sources in a given subject area do so, the symbols kWh, MWh, GWh are used ...
- And the reason it says that is MOSNUM's general provision that Unit names and symbols should follow the practice of reliable sources. We follow the practice of sources in the topic area. EEng (talk) 05:55, 31 July 2014 (UTC)
- Kilowatt is a SI unit, hour is accepted for use with the SI, so the appearance of "kW·h" is governed by the SI standards. If you can find a different "standard in the topic area", we can consider it to be more important, otherwise — rely on SI. The argument of "practice" is flawed, since it does not tell what to do if different "reliable" sources use different notation ("kWh", "KWH", "kW·h", "kW-hr", whatever)? — Mikhail Ryazanov (talk) 10:41 pm, Today (UTC−4)

{{convert}}
template to advocating the "alternative" notation in MOS. I suggest splitting his/her "proposal" into a separate topic and continuing here the original thread (which is related to conversion between different units, not to a particular unit itself). — Mikhail Ryazanov (talk) 03:38, 31 July 2014 (UTC)
- oh oh ... Mikhail, Ohconfucius appears to have removed this because it may impute wrongdoing to EEng without much evidence of it (as far as I can see). You've reverted it back in.

- Support original proposal. The MOS is not a voluntary set of guidelines; it's a style manual. Editors can follow it or not as they choose when creating text but must not undo changes made later to ensure consistency with the MOS. So MOSNUM should explicitly say that the commonly used forms like "kWh" are permitted. Peter coxhead (talk) 07:56, 31 July 2014 (UTC)
- Oppose for consistency and simplicity. We don't have to follow whatever we see out there. Jimp 11:50, 31 July 2014 (UTC)
- Yes, we do, as the next two Supports explain. It's only when there's a conflict between sources of comparable authoritativeness (in the field) that we make a choice of our own. EEng (talk) 16:00, 31 July 2014 (UTC)
- Support - The first bullet point of the MOS says, "Unit names and symbols should follow the practice of reliable sources." The proposal is simply codifying this. There are few sources that use the delicately punctuated versions. There is no significant ambiguity with the proposed symbols. ~KvnG 14:49, 31 July 2014 (UTC)
- "Delicately punctuated" is certainly the right phrase. EEng (talk) 16:20, 31 July 2014 (UTC)
- Support per Peter coxhead. It's a bit like MB and MiB: it makes no sense to have more than one ways of expressing kWh – the other different forms are hardly ever used in RL, and may confuse readers. -- Ohc ¡digame! 15:51, 31 July 2014 (UTC)
- Just to be clear, the proposal doesn't mandate using kWh (no space, no dot) exclusively, since I'm sure there are e.g. physics contexts in which space or dot is used. Rather, the proposal makes it clear that kWh is an acceptable choice, when it's what sources in the field use. EEng (talk) 16:00, 31 July 2014 (UTC)
- I think what we are discussing is whether one should use the symbol kW h or the abbreviation for that symbol kWh. I see no good reason not to use the symbol myself, but my opposition to use of the abbreviation is based on the desirability of clarity. The analogy with MB vs MiB is not a good one because MB and MiB are symbols that mean different things, and to use MB when you mean MiB is clearly incorrect. To use kWh when you mean kW h is not wrong, just an unnecessary barrier to clear communication. Dondervogel 2 (talk) 06:36, 1 August 2014 (UTC)

- Support Per common use, no we don't have to follow whatever we see in real life but we are writing an encyclopedia to be readily understood by as many of our readers as possible. Given that the majority of sources use it and most of our readers would be familiar with it is precisely why we should be using it. We should never use an abstract, unfamiliar form.

- Support as "kWh" is so prevalent in literature directed towards general and technical readers, while as noted by others J is preferred in much scientific literature. For information, checking some favourite print compendia of definitions, conversions and values I found "kWh" (Perry's Chemical Engineers Handbook, 6th edn, 1973, McGraw-Hill, Table 1-4 Conversion Factors; Larousse Dictionary of Science and Technology - previously published as Chambers (UK) or Cambridge (US), 1995, Larousse), "kw h" (BS350:Part 1:1974 Conversion factors and tables, British Standards Institution, 1974 (1998), p58; CRC Handbook of Chemistry and Physics, 68th edn, 1987, CRC Press, pF-245), and spaces used in other units but no example of "kW h" (Tables of Physical and Chemical Constants, Kaye & Laby, Longman, 15th ed, 1986), but no examples of "kW.h". NebY (talk) 11:58, 1 August 2014 (UTC)
- Oppose I don't see what's so difficult about "write metric units according to the SI convention"; there is no need to invent different rules for every unit (what is the rule for newton-metres? what about joule-seconds? etc.) and following convention promotes consistency, which aids intelligibility. If some people don't understand SI convention, that is not our responsibility. Ultimately the BIPM is the only authority on how unit notation should work; WP editors should not presume to know better than the organisation that maintains the standards. Archon 2488 (talk) 13:47, 1 August 2014 (UTC)
- Support A few contributors here feel that "exactitude" is more important than readability. Most reader's monthly electric bill will use kwh (with various forms of capitalization). The US Federal Energy Regulatory Commission uses KWh in their regulations.[8] The term "kW•h" will be unfamiliar to most readers and confusing to math majors trying to figure out why we are using a dot product in a unit of measure. We should not punish readers because they have never heard of "SI" units. Wikipedia should use the terminology that is in widespread use; not obscure terms from some standards committee. -- SWTPC6800 (talk) 22:03, 1 August 2014 (UTC)
- I don't think it's fair to describe the world's most important standards organisation, which is responsible for defining the SI units (and thereby, in effect, all others), together with the standard notation for using them, as "some ... committee". Archon 2488 (talk) 15:09, 2 August 2014 (UTC)
- SI may be an "important standards organisation" but some of their units are not widely used in publications targeted at the general public. Wikipedia articles targeted at the general public and should not be full of elitist terminology. (Some SI units are widely ignored in the technical press.) -- SWTPC6800 (talk) 16:31, 2 August 2014 (UTC)

Could you please find the actual official documents? (I'm also suspicious about the apparently interchangeable usage of "power" and "energy" in their language.)

- "exactitude" -- SWTPC6800 (talk) 02:14, 2 August 2014 (UTC)
- "We should not punish readers because they have never heard of "SI" units." If someone has heard of a kilowatt-hour, then they have heard of an SI unit (or at least, one of the SI's "addon" units). As Mikhail says above, the dot denotes scalar multiplication, and the product of two scalar physical dimensions is indeed a scalar product. I don't see how this is confusing. Even the idea behind omitting the space is that the multiplication is implicit, as in algebraic expressions like "2y". The question is simply which notation is the less ambiguous.

- Comment It think it's worth noting that not a single actual document or paper has been presented so far using anything other than kWh. EEng (talk) 03:51, 2 August 2014 (UTC)
- Because people advocating the consistency and standard-compliance understand that solitary examples are insufficient to make any conclusions about the general situation. Moreover, the existence of general standards (mentioned several times above) means that anything special about particular units is simply unnecessary. If you want to see something country-specific, here are some US-related documents:
- Federal Register notice of May 16, 2008, 73 FR 28432-28433. Interpretation of the International System of Units for the United States PDF,
- U.S. Metric System (SI) Legal Resources and references therein.
- People from other places can probably provide similar documents. If you claim something different, please provide the corresponding style guides or at least a reliable study about the "real-world usage" (so far, only poorly formatted texts have been presented as a supporting evidence). — Mikhail Ryazanov (talk) 04:45, 2 August 2014 (UTC)
- None of the documents you linked appear to contain the string kw so I don't see what they have to do with this at all. I repeat that you've never pointed to even a single use of kW-dot-h or kW-space-h. Not one. Just a lot of "standards" apparently implying dots or spaces ought to be used, but no evidence anyone actually obeys that. EEng (talk) 05:38, 2 August 2014 (UTC)
- Comment So here's sumtin' really interesting -- NIST's Rules and Style Conventions for Printing and Using Units. It says
- Reference [4: ISO 31-0] suggests that if a space is used to indicate units formed by multiplication, the space may be omitted if it does not cause confusion. This possibility is reflected in the common practice of using the symbol kWh rather than kW·h or kW h for the kilowatt hour. Nevertheless, this Guide takes the position that a half-high dot or a space should always be used to avoid possible confusion
- So there you have it. NIST says don't use kWh; ISO says it's OK (and so does APS [9]). The problem with appeals to the authority of standards bodies is that, contrary to what some seem to think, there is no one controlling standards body and, as just seen, they disagree. We use what workers in the field actually use, not what someone says they ought to use.
- I think the arguments on both sides have been thoroughly ventilated now, and it's time for a close based on the strength of those arguments. Anyone? EEng (talk) 05:38, 2 August 2014 (UTC)
- Congratulations, you have finally found reliable sources! :–) Just to supplement your comment, the NIST quote continues:
- ...; for this same reason, only one of these two allowed forms should be used in any given manuscript.
- (it is not clear whether this passage is about "kWh" or all units). And a small note: ISO 31-0:1992 was superseded with ISO 80000-1. Do you know whether the "suggestion" mentioned by NIST is still there? It would be interesting to see the actual wording. — Mikhail Ryazanov (talk) 07:03, 2 August 2014 (UTC)
- Not sure what you mean by "finally" -- if you think the other sources, to which I and several other editors have linked before now, aren't reliable then you don't know what a reliable source is. Anyway, I'll be happy to extend similar congratulations to you in return when you adduce even one source -- even one -- that actually uses the dot or space forms.

- I can offer you a source that uses a space if you want, but we all know such sources are rare, so I don't think it changes anything. I have stated before on this page that MOSNUM should follow international standards unless it has a good reason not to. This applies not just for the kilowatt hour, but for all units. I will look up the precise wording of ISO 80000-1:2009 on multiplication of units. Watch this space. Dondervogel 2 (talk) 08:19, 2 August 2014 (UTC)
- This search gives several hits for "kW h". I will look op iso 80000-1 next. Dondervogel 2 (talk) 08:25, 2 August 2014 (UTC)
- The relevant text from ISO 80000-1:2009 reads
- A compound unit formed by multiplication of two or more units shall be indicated in one of the following ways:
- N • m, N m
- NOTE The latter form may also be written without a space, i.e. Nm, provided that special care is taken when the symbol for one of the units is the same as the symbol for a prefix. This is the case for m, metre and milli, and for T, tesla and tera.
- While the wording could be clearer, I infer from this that kWh is a valid symbol for kilowatt hour and I withdraw my objection to the proposal to use it. Dondervogel 2 (talk) 08:30, 2 August 2014 (UTC)

-- [[User:Edokter]] {{talk}}
09:01, 2 August 2014 (UTC)
- Yes, but in the case of units these concatenations can lead to ambiguities such as ms-1. But in fairness, there is only one way to parse "kWh" in terms of the SI unit symbols, even if it's not really correct SI, so it's less important. Archon 2488 (talk) 15:09, 2 August 2014 (UTC)
- Comment. I will guess that some of the advocates of little-known SI units have never explained a new technology to an audience with mixed backgrounds. The key to success is to use terms the audience knows, not to impress them with technobabble. Wikipedia has an audience with a wide range of backgrounds. A reader with a Masters of Business Administration may want to read about power generation, they should not have to research the units. I am sure the financial community has some really esoteric terms from important standards originations that we could use to explain the cost of power production. -- SWTPC6800 (talk) 17:46, 2 August 2014 (UTC)
- The goal of consistent ways of making compound units in SI is to make it easier for people from different fields to understand unfamiliar units, because everyone writes them the same way.

If you stick with the BIPM standards and try to understand them, rather than just assuming the BIPM consists of a crowd of best-ignored inbred scientists and engineers who do nothing other than engage in intellectual masturbation, then you will understand the motivation for using consistent mathematical notation. Disambiguation. Precision. Unambiguity. But all of this is of second-rate importance compared to the goal of pandering to the innumerate. Archon 2488 (talk) 20:12, 2 August 2014 (UTC)
- "Nobody has explained how promoting inconsistency allows for greater intelligibility." Explanation: An article can't be consistent with everything, so choices must be made, and Wikipedia's choice is to value the intelligibility gained by consistency between a given article and external literature on the same topic, more than it values the intelligibility gained by consistency between that article and other articles on other topics.
- Since you bring it up, since BIPM stands for Best-Ignored Perfectionist Masturbators (formerly BIISE -- Best-Ignored Inbred Scientists and Engineers) what did you expect? I really think it would be for the best if someone closes this discussion before the inevitable comparisons to Nazis make their debut.

Microsoft is more important than IBM and Toshiba
It is for the best that editors remain unaware that IBM and Toshiba use unambiguous binary prefixes, because (shock, horror, probe!) they might start to use them themselves, and we wouldn't want that, would we? Dondervogel 2 (talk) 21:26, 1 August 2014 (UTC)
For further clarification, according to IBM:
- Decimal units (base-10), such as K, MB, GB, and TB, are commonly used to express data storage values. These values, however, are more accurately expressed using binary units (base-2), such as KiB, MiB, GiB, and TiB. At the kilobyte level, the difference between decimal and binary units of measurement is relatively small (2.4%). This difference grows as data storage values increase. When values reach terabyte levels, the difference between decimal and binary units approaches 10%.
- To avoid confusion, the online LTFS Single Drive Edition product documentation represents data storage using both decimal and binary units. Data storage values are displayed using the following format:#### decimal unit (binary unit)
- For example, a value of 512 terabytes is displayed: 512 TB (465.6 TiB)
It is for the best that Wikipedia editors remain ignorant of the benefits of IEC prefixes. Dondervogel 2 (talk) 21:40, 1 August 2014 (UTC)
- Please read WP:RIGHTGREATWRONGS. What you added, even if the statements are accurate (I didn't check; many such statements added have been faked), have no place in the MOS. They may be used on the MOS talk page to attempt to justify a change in the MOS, but they do not belong in the MoS. — Arthur Rubin (talk) 23:13, 1 August 2014 (UTC)
