A calorie is still 4.18... Joules whether in food or in physics homework. It's just that nobody says "kilocalories" even though the label says "kcal" ;)

- roel_v 11y agoNo. A 'food calorie' ('1 Cal') = 1000 calories ('1000 cals').
- lorenzhs 11y agoInteresting, the American usage seems to be quite different from usage in Germany. There is no such thing as a "food calorie" here, they're labelled as "kcal" (kilocalories). From the German Wikipedia article on "Kalorie": > Umgangssprachlich werden oft Nährwertangaben in Kilokalorien fälschlich > als „Kalorien“ bezeichnet. In den USA ist bei Nährwertangaben > die Bezeichnung calorie für Kilokalorien auch offiziell zulässig. In English: Informally, kilocalories in food are often referred to simply as "calories". In the USA, using "calories" instead of "kilocalories" in nutritional information is officially allowed. Here it's not allowed to label them as calories, they have to be labelled as kilocalories. They're still called "calories" informally though.
