Convert megaelectron-volt to joule
Please provide values below to convert megaelectron-volt [MeV] to joule [J], or Convert joule to megaelectron-volt.
1 MeV = 1.6022e-13 J. To convert megaelectron-volt to joule, multiply the value by 1.6022e-13; to go the other way, divide by it (1 J = 6.2415e+12 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-13 J
- 1 J = 6.2415e+12 MeV
- 10 MeV = 1.6022e-12 J
- 100 MeV = 1.6022e-11 J

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.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
