Kilojoules to Kilocalories Converter

Enter the energy in kilojoules below to convert it to kilocalories.

Result in Kilocalories:

1 kJ = 0.239006 kcal

How to Convert Kilojoules to Kilocalories

To convert a measurement in kilojoules to a measurement in kilocalories, multiply the energy by the following conversion ratio: 0.239006 kilocalories/kilojoule.

Since one kilojoule is equal to 0.239006 kilocalories, you can use this simple formula to convert:

kilocalories = kilojoules × 0.239006

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

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

kilocalories = (5 kJ × 0.239006) = 1.195029 kcal

How Many Kilocalories Are in a Kilojoule?

There are 0.239006 kilocalories in a kilojoule, which is why we use this value in the formula above.

1 kJ = 0.239006 kcal

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

What Is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is 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 thousands, or 10³. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

What Is a Kilocalorie?

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.
