Convert megaelectron-volt to gigajoule
Please provide values below to convert megaelectron-volt [MeV] to gigajoule [GJ], or Convert gigajoule to megaelectron-volt.
1 MeV = 1.6022e-22 GJ. To convert megaelectron-volt to gigajoule, multiply the value by 1.6022e-22; to go the other way, divide by it (1 GJ = 6.2415e+21 MeV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 MeV = 1.6022e-22 GJ
- 1 GJ = 6.2415e+21 MeV
- 10 MeV = 1.6022e-21 GJ
- 100 MeV = 1.6022e-20 GJ
How to Convert Megaelectron-Volt to Gigajoule

Megaelectron-Volt
A megaelectron-volt (MeV) is a unit of energy equal to one million electron-volts, commonly used in nuclear and particle physics to express the energy of particles.
History/Origin
The megaelectron-volt was introduced as a convenient unit for expressing high-energy particles in physics, particularly after the development of particle accelerators in the mid-20th century, replacing the electron-volt for larger energy scales.
Current Use
Today, the MeV is widely used in nuclear physics, particle physics, and astrophysics to quantify the energy of subatomic particles, nuclear reactions, and cosmic phenomena.
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.
