How to Convert Megajoules to Calories

To convert a megajoule measurement to a calorie measurement, multiply the energy by the conversion ratio.

Since one megajoule is equal to 239,005.736138 calories, you can use this simple formula to convert:

calories = megajoules × 239,005.736138

The energy in calories is equal to the megajoules multiplied by 239,005.736138.

For example, here's how to convert 5 megajoules to calories using the formula above.
5 MJ = (5 × 239,005.736138) = 1,195,028.680688 cal

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


One megajoule is equal to 1,000,000 joules, which are 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 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.


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.
