Convert megajoule to gigajoule
Please provide values below to convert megajoule [MJ] to gigajoule [GJ], or Convert gigajoule to megajoule.
1 MJ = 0.001 GJ. To convert megajoule to gigajoule, multiply the value by 0.001; to go the other way, divide by it (1 GJ = 1000 MJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 MJ = 0.001 GJ
- 1 GJ = 1000 MJ
- 10 MJ = 0.01 GJ
- 100 MJ = 0.1 GJ
How to Convert Megajoule to Gigajoule
1 MJ = 0.001 GJ
Example: convert 15 MJ to GJ:
15 MJ = 15 × 0.001 GJ = 0.015 GJ

Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
