How to Convert Kilojoules to Kilocalories

To convert a kilojoule measurement to a kilocalorie measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 0.239006 kilocalories, so use this simple formula to convert:

kilocalories = kilojoules × 0.239006

The energy in kilocalories is equal to the kilojoules multiplied by 0.239006.

For example, here's how to convert 5 kilojoules to kilocalories using the formula above.
5 kJ = (5 × 0.239006) = 1.195029 kcal

Kilojoules and kilocalories 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 103. Kilojoules can be abbreviated as kJ, for example 1 kilojoule can be written as 1 kJ.

Kilocalories

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal, for example 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.
