What are calories?

Submitted by: Muhammad

Used as a unitary measure of energy. A ‘small calorie' is the energy required to raise the temperature of one gram of water by a degree celsius.

A ‘kilogram calorie' (kcal) is the unit the term ‘calorie' generally refers to. This is equivalent to 1,000 small calories.
