## How to Convert Gigajoules to Megajoules

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

Since one gigajoule is equal to 1,000 megajoules, you can use this simple formula to convert:

The energy in megajoules is equal to the gigajoules multiplied by 1,000.

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

### How Many Megajoules are in a Gigajoule?

There are **1,000** megajoules in a gigajoule, which is why we use this value in the formula above.

1 GJ = 1,000 MJ

Gigajoules and megajoules 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.

## 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^{6}. Megajoules can be abbreviated as *MJ*; for example, 1 megajoule can be written as 1 MJ.
