Megawatt-hours to Electronvolts Converter

Convert megawatt-hours (MWh) 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.

Show the working
  1. 1 MWh = 2.24694326681e28 eV
  2. 1 × 2.24694326681e28 = 2.24694326681e28 eV

How to convert megawatt-hours to electronvolts

1 MWh = 2.24694326681 × 10²⁸ eV, so multiply by 2.24694326681 to go from megawatt-hours to electronvolts. Going the other way, 1 eV = 4.45049065 × 10⁻²⁹ MWh.

eV = MWh × 2.24694326681
MWh = eV × 4.45049065

Worked example:

1 MWh = 2.24694326681e28 eV
5 × 2.24694326681e28 = 1.1234716334e29 eV
