How to convert megaelectronvolts to megawatt-hours

1 MeV = 4.45049065 × 10⁻²³ MWh, so multiply by 4.45049065 to go from megaelectronvolts to megawatt-hours. Going the other way, 1 MWh = 2.24694326681 × 10²² MeV.

MWh = MeV × 4.45049065
MeV = MWh × 2.24694326681

Worked example:

1 MeV = 4.45049065e-23 MWh
5 × 4.45049065e-23 = 2.225245325e-22 MWh
