The One & Only Calorie With An Exact kWh Equivalent

Some time ago, I corrected the article, setting the International Steam Table calorie (1956) exactly equal to 1.163 mWh, by merely replacing the wavy equal sign "≈" with the regular "=" sign. This pleasant feature may be the reason why it is the calorie preferred by dieters, as kilocalorie:

       1 Cal = 1.163Wh.

So Russ Rowlett in his former UNC tables of constants. This may have been the shortest possible Wikipedia edit, ever...!! hgwb 12:25, 11 March 2019 (UTC)

National differences

My observation is that in the US the kilocalorie is officially preferred (e.g. in product labelling), whereas in Australia there is an official preference for the kilojoule (although the kilocalorie is still widely used, especially due to the pervasive US influence on Australian culture and businesses.) I think some discussion of national differences in the use of energy units (at least in the field of food, exercise and nutrition) would be a valuable addition to the article.

Calorie = 4.1868 J in the EU

In the European Union

1. the official unit is joule
2. calorie may be on the label (only) in addition. In this case, "calorie" is always the small calorie, i.e. 4.1868 J. This has been fixed by EU law in 1971 (). Hence 4186.8 J is "kcal" and only "kcal" -- Wassermaus (talk) 20:55, 3 July 2020 (UTC)

Says who?

How, when and by whom was it determined that the amount of calories consumed is related to one's weight?

And does food really "contain" calories? 199.192.151.199 (talk) 15:41, 3 June 2025 (UTC)

Added "See also" reference to another article

I added "Calorie deficit" to the See also section because it's a directly related concept not covered in the main article. I think readers looking into "calorie" might benefit from seeing it linked. MintyGreenTea (talk) 11:37, 9 July 2025 (UTC)

Obsolescence

I added the word obsolete, again, in the description, as the article itself says so.

@Wesko, the article says it is obsolescent in physics and chemistry. It is NOT obsolescent in nutrition where it is still in use, so your change is incorrect. StarryGrandma (talk) 00:22, 10 November 2025 (UTC)

@StarryGrandma

Ok, thx.

Picture

I feel that the picture for this article does not represent the topic well. The lable with the calories is not in full view, you have to look closely to actually see the calorie count. Sentienceglobe (talk) 16:49, 22 March 2026 (UTC)

Agree and changed with Special:Diff/1344853979. An image specifically about a 'calorie' is not present on Wikimedia Commons, so a representative food label can be used. Zefr (talk) 23:21, 22 March 2026 (UTC)
