Gigajoules to Megajoules Conversion
Enter the energy in gigajoules below to get the value converted to megajoules.
How to Convert Gigajoules to Megajoules
To convert a gigajoule measurement to a megajoule measurement, multiply the energy by the conversion ratio.
Since one gigajoule is equal to 1,000 megajoules, you can use this simple formula to convert:
The energy in megajoules is equal to the gigajoules multiplied by 1,000.
How Many Megajoules are in a Gigajoule?
There are 1,000 megajoules in a gigajoule, which is why we use this value in the formula above.
1 GJ = 1,000 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 109. 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 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.
