What is the difference between a heat calorie and a food calorie?
Answered by Hannah
A 'heat calorie' is the amount of energy it takes to heat 1 mL of water 1 degree celsius. This is the 'real' calorie.

A food calorie is 1000 heat calories. 1 food calorie is written as 1 C. So when you eat something with '150 calories', you're actually eating 150000 heat calories.
