kilo joules are used but sometimes calories are also used.
Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
The recommended unit for any type of energy is, of course, the joule. The older unit, calorie, is still often used for food. If spelled with a capital "C", "Calorie", it usually means a kilocalorie.
Calories are the unit of energy used to measure how much energy is present in food. One calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
The international unit for energy is the joule. Specifically for food, an old-fashioned unit, the kilocalorie (often just written Calorie, with an uppercase "C"), is often used instead. One kilocalorie is about 4200 joules.
1) The unit for any type of energy is the joule. 2) In some contexts, such as food, the old-fashioned unit "calorie" is still used.
THE ANSWER IS kilojoules hope it helped!
KiloCalories and KiloJoules.
The unit of energy found on food packets is typically measured in kilocalories (kcal) or kilojoules (kJ). Kilocalories are more commonly used in the United States, while kilojoules are more common in other countries. One kilocalorie is equivalent to 4.184 kilojoules.
Calorie is the unit used to express chemical energy in food.
Probably one packet.
Any unit of energy can be used to describe the energy content of food.

"Calorie" is not a chemical name but instead is a unit of the energy value that be obtained from food. Since any food sufficient to sustain life can provide calories for energy to the organism that consumes the food, almost any element (except the noble gases) can be a source of calories, but a calorie is a unit of the abstract concept energy rather than a material substance and therefore can not be "found" in food in the usual meaning of that phrase.
