Megaelectronvolts to Electronvolts Converter

Convert megaelectronvolts (MeV) to electronvolts (eV), 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 megaelectronvolts to electronvolts

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

eV = MeV × 1,000,000
MeV = eV × 1

Worked example:

1 MeV = 1000000 eV
5 × 1000000 = 5000000 eV
