How to Convert Electron Volt to Megaelectron Volt

To convert from Electron Volt (eV) to Megaelectron Volt (MeV), multiply the value by 1.000000e-6.

Formula: MeV = eV × 0.000001

Reverse: eV = MeV × 1,000,000.0000000001

Step-by-Step Example

Start with your value in Electron Volt. For example: 5 eV
Multiply by the conversion factor: 5 x 1.000000e-6
The result is: 5.000000e-6 MeV

About Electron Volt

The electron volt (eV) is a unit of energy and work. One electron volt equals 1.602177 × 10^-19 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.

About Megaelectron Volt

The megaelectron volt (MeV) is a unit of energy and work. One megaelectron volt equals 1.602177 × 10^-13 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.
