To convert a measurement in megajoules to a measurement in calories, multiply the energy by the following conversion ratio: 239,005.736138 calories/megajoule.

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 energy in megajoules multiplied by 239,005.736138.

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

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 Calorie?

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.
