## How to Convert Gigajoules to Megacalories

To convert a measurement in gigajoules to a measurement in megacalories, multiply the energy by the following conversion ratio: 239.005736 megacalories/gigajoule.

Since one gigajoule is equal to 239.005736 megacalories, you can use this simple formula to convert:

megacalories = gigajoules × 239.005736

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

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

### How Many Megacalories Are in a Gigajoule?

There are **239.005736** megacalories in a gigajoule, which is why we use this value in the formula above.

1 GJ = 239.005736 Mcal

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

## What Is a Gigajoule?

One gigajoule is equal to 1,000,000,000 joules, which is 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 billions, or 10^{9}. Gigajoules can be abbreviated as *GJ*; for example, 1 gigajoule can be written as 1 GJ.

## What Is a Megacalorie?

One megacalorie is equal to 1,000,000 calories, which is 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.
