section::::units.:calories.









































in chemistry, heat amounts are often measured in calories. confusingly, two units with that name, denoted "cal" or "cal", have been commonly used to measure amounts of heat: 









































bullet::::- the "small calorie" (or "gram-calorie", "cal") is 4.184 j, exactly. it was originally defined so that the heat capacity of 1 gram of liquid water would be 1 cal/°c.









































bullet::::- the "grand calorie" (also "kilocalorie", "kilogram-calorie", or "food calorie"; "kcal" or "cal") is 1000 small calories, that is, 4184 j, exactly. it was originally defined so that the heat capacity of 1 kg of water would be 1 kcal/°c.
