Calories:

A unit of energy is called calories.
1 calorie equals 4.2 Jules.
Actually, a "kilocalorie" is a "calorie" from food.
In other words, it is the amount of energy required to raise a litre of water's temperature by one degree.
A device in which heat measurement can be done is called a calorimeter.

Thus, the energy value of food is measured in the unit of calories.
