## How to Convert Kilojoules to Calories

To convert a kilojoule measurement to a calorie measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 239.005736 calories, so use this simple formula to convert:

The energy in calories is equal to the kilojoules multiplied by 239.005736.

**For example,**here's how to convert 5 kilojoules to calories using the formula above.

Kilojoules and calories are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Kilojoules

One kilojoule is equal to 1,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for 10^{3}. Kilojoules can be abbreviated as *kJ*; for example, 1 kilojoule can be written as 1 kJ.

## Calories

One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.

When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."

Calories can be abbreviated as *cal*; for example, 1 calorie can be written as 1 cal.
