How to convert electronvolts to megawatt-hours

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

MWh = eV × 4.45049065
eV = MWh × 2.24694326681

Worked example:

1 eV = 4.45049065e-29 MWh
5 × 4.45049065e-29 = 2.225245325e-28 MWh
