MeV to eV Converter
Convert megaelectron-volts to electron-volts quickly and accurately
Conversion Formula
The relationship between megaelectron-volts and electron-volts is straightforward:
Where E(eV) is the energy in electron-volts and E(MeV) is the energy in megaelectron-volts. The prefix “mega” represents a factor of 10⁶ (one million).
Conversion Examples
Calculation: 5 MeV × 1,000,000 = 5,000,000 eV
Result: 5 MeV = 5,000,000 eV
Calculation: 0.5 MeV × 1,000,000 = 500,000 eV
Result: 0.5 MeV = 500,000 eV
Calculation: 2.5 MeV × 1,000,000 = 2,500,000 eV
Result: 2.5 MeV = 2,500,000 eV
Calculation: 0.001 MeV × 1,000,000 = 1,000 eV
Result: 0.001 MeV = 1,000 eV

About Electron-Volt (eV) and Megaelectron-Volt (MeV)
What is an Electron-Volt?
The electron-volt (eV) is a unit of energy commonly used in atomic and nuclear physics. It is defined as the amount of kinetic energy gained by a single electron when accelerated through an electric potential difference of one volt. One electron-volt equals approximately 1.602 × 10⁻¹⁹ joules.
What is a Megaelectron-Volt?
The megaelectron-volt (MeV) is a larger unit of energy equal to one million electron-volts. This unit is particularly useful in nuclear physics and particle physics, where energy levels are significantly higher than in atomic physics. Nuclear reactions, gamma rays, and high-energy particles are commonly measured in MeV.
Applications in Physics
MeV and eV are extensively used across various fields of physics:
- Nuclear Physics: Nuclear binding energies, fission, and fusion reactions are typically measured in MeV
- Particle Physics: Rest mass energies of particles and collision energies are expressed in MeV or GeV
- Medical Physics: Radiation therapy and medical imaging utilize MeV-range photons and particles
- Atomic Physics: Ionization energies and atomic transitions are measured in eV
- Solid State Physics: Band gaps in semiconductors are typically expressed in eV
