## How to Convert Joules to Gigajoules

To convert a measurement in joules to a measurement in gigajoules, divide the energy by the following conversion ratio: 1,000,000,000 joules/gigajoule.

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

gigajoules = joules ÷ 1,000,000,000

The energy in gigajoules is equal to the energy in joules divided by 1,000,000,000.

**For example,**here's how to convert 5,000,000,000 joules to gigajoules using the formula above.

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

## What Is a Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.^{[1]} One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*; for example, 1 joule can be written as 1 J.

## 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.
