The precise equivalence between calories and joules has varied over the years, but in thermochemistry and nutrition it is now generally assumed that one (small) calorie (thermochemical calorie) is equal to exactly 4.184 J, and therefore one kilocalorie (one large calorie) is 4184 J or 4.184 kJ.
The "grand calorie" (also "kilocalorie", "kilogram-calorie", or "food calorie"; "kcal" or "Cal") is 1000 small calories, that is, 4184 J, exactly. When heat is measured in these units, the unit of specific heat is usually 1 cal/(°C⋅mol) ("small calorie") = 4.184 J⋅K −1 ⋅mol −1 1 kcal/(°C⋅mol) ("large calorie") = 4184 J⋅K −1 ...
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
It has been believed that there are 3,500 calories in a pound, so therefore it would seem that if you reduce your diet by 500 calories a day or exercise and burn off 500 calories a day (or any ...
the small calorie (gram-calorie, cal) is 4.184 J exactly. It was originally defined so that the specific heat capacity of liquid water would be 1 cal/(°C⋅g). The grand calorie (kilocalorie, kilogram-calorie, food calorie, kcal, Cal) is 1000 small calories, 4184 J exactly. It was defined so that the specific heat capacity of water would be 1 ...
For example, if you typically consume 3,500 calories per day, in order to lose a pound per week, you might shave 500 calories off of your daily caloric intake in order to lower your daily average ...
