Electronvolts to Megaelectronvolts Converter

Convert electronvolts (eV) to megaelectronvolts (MeV), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

How to convert electronvolts to megaelectronvolts

1 eV = 1 × 10⁻⁶ MeV, so multiply by 1 to go from electronvolts to megaelectronvolts. Going the other way, 1 MeV = 1,000,000 eV.

MeV = eV × 1
eV = MeV × 1,000,000

Worked example:

1 eV = 1e-6 MeV
5 × 1e-6 = 5e-6 MeV
