How to Convert Megajoules to Gigajoules

To convert a megajoule measurement to a gigajoule measurement, multiply the energy by the conversion ratio. One megajoule is equal to 0.001 gigajoules, so use this simple formula to convert:

gigajoules = megajoules × 0.001

The energy in gigajoules is equal to the megajoules multiplied by 0.001.

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

5 MJ = (5 × 0.001) = 0.005 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 10⁹. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.

Gigajoules
