## How to Convert Calories to Megajoules

To convert a calorie measurement to a megajoule measurement, multiply the energy by the conversion ratio. One calorie is equal to 4.184E-6 megajoules, so use this simple formula to convert:

The energy in megajoules is equal to the calories multiplied by 4.184E-6.

**For example,**here's how to convert 5 calories to megajoules using the formula above.

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

## Calories

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.

## Megajoules

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 10^{9}. Megajoules can be abbreviated as *MJ*, for example 1 megajoule can be written as 1 MJ.
