What is Calorie (IT)?

The calorie (symbol: cal) is a unit of energy that was originally defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere.

Note that this unit is the “small calorie.” The calorie typically seen on food labels is the “large calorie” or kilocalorie (kcal).

Common Uses

Calories are primarily used in the fields of chemistry and physics. In nutrition, the kilocalorie (often just called “Calorie”) is the standard unit for measuring the energy people get from eating and drinking.

What is Kilojoule?

The kilojoule (symbol: kJ) is a decimal multiple of the joule, the SI unit of energy.

One kilojoule is equal to 1,000 joules.

Common Uses

Kilojoules are commonly used to express the energy content of foods (as an alternative to calories) and in many engineering and industrial contexts to measure larger amounts of energy.

How many kilojoule are in a calorie (it)?

There are 0.0041868 kilojoule in 1 calorie (it).
