1 kilojoule (kj) = 0.2389 kilocalorie (kcal).

Kj is equal to 0.2389 kilocalories. Calorie is abbreviated as cal, which is transliterated from English. It is defined as the heat required to raise 1 gram of water by 1 degree Celsius at 1 atmospheric pressure; a calorie is a unit of heat that is widely used in nutritional measurement and fitness manuals. The international standard unit of energy is joules. As the legal unit of food calories, the joule is commonly used in Europe, and the calorie is used in the United States.

Heat and work are two different forms of energy transfer that occur during system state changes. They are measures of different forms of energy transfer. They are both related to the intermediate process of state change and are therefore not functions of the system state. . Calories: 1 kilocalorie (KCAL) = 4.184 kilojoules (KJ), 1 kilojoule (KJ) = 0.239 kilocalorie (KCAL).

Kj related introduction:

"KJ" is the abbreviation of the English unit name "kilojoules", which represents a thousand times of joules. Joule is a unit of energy in physics, used to express the energy an object has or the work it can perform. 1 Joule is equal to 1 Newton meter, or the work done by Newton's force pushing an object along a distance of 1 meter.

The "kilojoule (kJ)" is one thousand times the joule and is usually used to represent the measurement unit of thermal energy, food energy, mechanical energy, etc. In food nutrition, 1 kilojoule is equivalent to 239 kilocalories and is one of the most commonly used energy units. For example, the kilojoules and calories marked on a food package are used to indicate the energy calories provided by the food.
