## How to Convert Gigajoules to Megacalories

To convert a gigajoule measurement to a megacalorie measurement, multiply the energy by the conversion ratio. One gigajoule is equal to 239.005736 megacalories, so use this simple formula to convert:

The energy in megacalories is equal to the gigajoules multiplied by 239.005736.

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

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

## Gigajoules

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

The gigajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "giga" is the prefix for 10^{9}. Gigajoules can be abbreviated as *GJ*, for example 1 gigajoule can be written as 1 GJ.

## Megacalories

One megacalorie is equal to 1,000,000 calories, which are the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius. One megacalorie is equal to 4.184 megajoules.

Megacalories can be abbreviated as *Mcal*, for example 1 megacalorie can be written as 1 Mcal.
