# Gigajoules to Kilojoules Conversion

Enter the energy in gigajoules below to get the value converted to kilojoules.

Results in Kilojoules: 1 GJ = 1,000,000 kJ

## How to Convert Gigajoules to Kilojoules

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

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

kilojoules = gigajoules × 1,000,000

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

For example, here's how to convert 5 gigajoules to kilojoules using the formula above.
5 GJ = (5 × 1,000,000) = 5,000,000 kJ

### How Many Kilojoules Are in a Gigajoule?

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

1 GJ = 1,000,000 kJ

Gigajoules and kilojoules 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 109. Gigajoules can be abbreviated as GJ; for example, 1 gigajoule can be written as 1 GJ.

## Kilojoules

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

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.
