[edit] Positive sign
Is that necessary? —MJCdetroit 04:11, 16 March 2007 (UTC)
- From what I remember being taught in high school :), the positive sign must precede degrees Centigrade above zero, unless the value is used informally (casual email, passing reference, etc). I might be wrong, though.—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); 12:14, 16 March 2007 (UTC)
- I probably didn't go to the same high school but it seems that the positive sign would only be applied to only the most highly scientific or technical of writings and not a general writing (like an encyclopedia). I deal with technical writings (automotive and military specifications) all day at work and they never use a + sign in front a temperature; even when stated in a range with a negative temperature (e.g -30°C to 150°C). I used this template and some others at Warsaw; check it out. —MJCdetroit 17:56, 16 March 2007 (UTC)
- Do you think this could be due to the fact that most of the technical writings you work with were written by Americans, for whom Centigrade is the "second language"? The writers may just unconciously be transferring the formatting rules for degrees Fahrenheit, for which, to the best of my knowledge, the plus sign is not only optional, but is not recommended. I'm just speculating here, of course, but I wouldn't be surprised if this were the exact reason why. Anyway, this needs further checking. I could, of course, add another parameter (plus=yes/no), but I am hesitant to make changes to the template one way or another without knowing for sure what would be right.—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); 18:38, 16 March 2007 (UTC)
- I would have to disagree because the DIN specs are written by Germans and they do not have the + sign in front of the temperatures (I am looking at DIN 267 part 27 at the moment). I guess, we should see how encyclopedia Brittanica and Encarta does it.

- Also, have you tried the abbr = MOS option for these templates yet? —MJCdetroit 20:12, 16 March 2007 (UTC)

- I looked both Brittanica and Encarta don't use the the plus sign but interestingly enough the original German of the DIN specs do use the + sign. So it maybe an English/foreign language thing. —MJCdetroit 20:26, 16 March 2007 (UTC)

- It shouldn't have the + sign. If you have something that for some reason should have the plus sign, it is rare enough to do it without using the template. It is not something required Gene Nygaard 22:10, 19 March 2007 (UTC)
- May I ask what you are basing this statement on, please? I am also wondering about this edit of yours—you inserted a space between the number and (unwikified) degree Fahrenheit, but not between the number and (unwikified) degree Celsius. Did you just overlook the other one, or is there some other reason behind this? Thanks!—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); 22:18, 19 March 2007 (UTC)

- It is obviously a misbelief that there is a rule saying that it should be there. There isn't, and nobody has cited one.
- I just didn't scroll the page over to see the missing space for the °C. Gene Nygaard 01:52, 20 March 2007 (UTC)
- I am sorry, it isn't obvious to me at all. Plus (pardon the pun), if there is no rule either way, then it shouldn't matter whether we use a plus sign or not. On the other hand, if there is a rule, we need to find it and apply it. As for the missing spaces—thanks for catching them up; my bad.—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); 02:08, 20 March 2007 (UTC)
- I've never seen nor heard of such a rule nor can I recall ever seeing a plus sign before a value in degrees Celsius and Celsius is what I grew up with. Now suppose this were removed from the template and for some reason or other you actually want the plus sign. There'd be no need to worry about special parameters nor would you have to just not use the template. The solution is very simple: just include the plus sign in the input, like this
{{C to F|+20|C}}. To see what I mean, take {{F to C}}{{F to C|20}}gives you "20°F (−6.7°C)" but{{F to C|+20}}gives you "+20°F (−6.7°C)".

- That's a great work-around, but I'd really, really, really prefer seeing something in print that says something like "use the plus sign", "do not use the plus sign", or "use the plus sign in such and such cases and do not use it in such and such cases". Until we find the reference, any approach would be nothing more than a guesswork.—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); 15:50, 23 January 2008 (UTC)
- 'Twould be nice but in the absence of such my guess would be to treat this like anything else and only add the plus sign in case it's needed. Jɪmp 16:19, 23 January 2008 (UTC)
- Well, alright. Feel free to fix it up, although I still don't see any problems with the plus sign showing by default (perhaps it's because it was customary where I grew up :)).—Ëzhiki (Igels Hérissonovich Ïzhakoff-Amursky) • (yo?); 15:01, 24 January 2008 (UTC)
