How to Convert Gigajoules to Kilojoules

To convert a gigajoule measurement to a kilojoule measurement, multiply the energy by the conversion ratio. One gigajoule is equal to 1,000,000 kilojoules, so 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

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.
