Definition of Calorie
Calorie: A unit of food energy. The word calorie is ordinarily used instead of the more precise, scientific term kilocalorie. A kilocalorie represents the amount of energy required to raise the temperature of a liter of water 1' centigrade at sea level. Technically, a kilocalorie represents 1,000 true calories of energy.
