What are calories?

Calorie is a unit of measuring energy. One calorie is the energy that can raise the temperature of one gram of water by one degree celsius.

When we talk about energy from foods, we generally use the term kilocalories (abbreviated as kCal), or simply make the first letter capital to signify a bigger unit (Calories).

Thus, 1000 caories = 1 Calorie.

The SI unit of energy is Joule (abbreviated as J)

1kcal = 4184 J

1 J = 0.24 kcal = 240 calories

The following table will give you an idea of how much calories a particular food contains.
