In order to answer this question, it helps to define a calorie. A calorie is a unit that is used to measure energy. The Calorie you see on a food package is actually a kilocalorie, or 1,000 calories. A Calorie (kcal) is the amount of energy needed to raise the temperature of 1 kilogram of water 1 degree Celsius.Sometimes the energy content of food is expressed in kilojoules (kj), a metric unit.One kcal equals 4.184 kj.So the Calorie on a food package is 1,000 times larger than the calorie used in chemistry and physics.ometimes the energy content of food is expressed in kilojoules (kj), a metric unit.
