How to Convert Kilojoules to Gigajoules

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

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

gigajoules = kilojoules ÷ 1,000,000

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

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

gigajoules = (5,000,000 kJ ÷ 1,000,000) = 5 GJ

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

What Is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is 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 thousands, or 10³. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

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