Calorie : The calorie is a pre-SI metric unit of energy. Its symbol is cal, and first defined as a unit of heat by Nicolas Clément in 1824. The calorie is commonly used in the field of chemistry, and in many countries it is commonly used as a unit of food energy. There are two defined for the calorie, gram calorie (approximately equals 4.2 joules) and kilogram calorie (approximately equals 4.2 kilojoules).

Joule : Joule is a derived unit of energy, work, or amount of heat in the international system of units. Its symbol is J. In the energy unit system, it is equal to the energy expended in applying a force of one newton through a distance of one meter. The unit name “joule” is in honor of the English physicist James Prescott Joule.

### FAQ about Calorie to Joule Conversion

1 calorie (cal) is equal to 4.1868 joule (J).

1cal = 4.1868J

The Energy E in joule (J) is equal to the Energy E in calorie (cal) times 4.1868, that conversion formula:

E(J) = E(cal) × 4.1868

One Calorie is equal to 4.1868 Joule:

1cal = 1cal × 4.1868 = 4.1868J

One Joule is equal to 0.23885 Calorie:

1J = 1J × 0.23885 = 0.23885cal

E(J) = 5(cal) × 4.1868 = 20.934J
