How to Convert Gigajoules to Megajoules

To convert a gigajoule measurement to a megajoule measurement, multiply the energy by the conversion ratio. One gigajoule is equal to 1,000 megajoules, so use this simple formula to convert:

megajoules = gigajoules × 1,000

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.
5 GJ = (5 × 1,000) = 5,000 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 106. 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 109. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.
