The joule.
If you refer to the unit, the international unit for energy is the joule; the symbol is "J".
The unit used to measure the energy of an electromagnetic wave is called a photon.
The international unit for energy (and work) is the joule.
Calorie is the unit used to express chemical energy in food.
The unit used for ANY type of energy is the joule.
The unit used to measure thermal energy besides joules is the calorie. It is commonly used to quantify the energy content in food and beverages.
work and energy +++ The Joule (J) is the unit of energy, alone, not of work. The Watt (W) is the unit of power, i.e. work done in converting or transferring energy, and 1W = 1J/s.
A kilocalorie is not a measure of weight. It is a measure of energy
Energy of heat = Joules (J)
The unit used to measure kinetic energy is the joule (J).

Kilo joules are used to measure the amount of energy stored in food.
