More Information
Food energy is primarily measured in kilocalories (kcal), also known as Calories (capital C). In some countries, kilojoules (kJ) are also commonly used as a measure of food energy, as the joule is the SI unit of energy.

A common mistake is confusing calories with kilocalories; in food energy, 1 Calorie (with a capital C) is actually equivalent to 1 kilocalorie.
