How to Convert Megajoules to Kilocalories

To convert a measurement in megajoules to a measurement in kilocalories, multiply the energy by the following conversion ratio: 239.005736 kilocalories/megajoule.

Since one megajoule is equal to 239.005736 kilocalories, you can use this simple formula to convert:

kilocalories = megajoules × 239.005736

The energy in kilocalories is equal to the energy in megajoules multiplied by 239.005736.

For example, here's how to convert 5 megajoules to kilocalories using the formula above.
kilocalories = (5 MJ × 239.005736) = 1,195.028681 kcal

How Many Kilocalories Are in a Megajoule?

1 MJ = 239.005736 kcal

What Is a Megajoule?

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

The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for millions, or 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.

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.
