How to Convert Megajoules to Gigajoules

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

gigajoules = megajoules ÷ 1,000

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

For example, here's how to convert 5,000 megajoules to gigajoules using the formula above.
5,000 MJ = (5,000 ÷ 1,000) = 5 GJ

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

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 106. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.

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.
