Convert megaelectron-volt to megajoule
Please provide values below to convert megaelectron-volt [MeV] to megajoule [MJ], or Convert megajoule to megaelectron-volt.
1 MeV = 1.6022e-19 MJ. To convert megaelectron-volt to megajoule, multiply the value by 1.6022e-19; to go the other way, divide by it (1 MJ = 6.2415e+18 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-19 MJ

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.
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.
