  1. 1 MeV = 4.45049065e-20 kWh
  2. 1 × 4.45049065e-20 = 4.45049065e-20 kWh

How to convert megaelectronvolts to kilowatt-hours

1 MeV = 4.45049065 × 10⁻²⁰ kWh, so multiply by 4.45049065 to go from megaelectronvolts to kilowatt-hours. Going the other way, 1 kWh = 2.24694326681 × 10¹⁹ MeV.

kWh = MeV × 4.45049065
MeV = kWh × 2.24694326681

Worked example:

1 MeV = 4.45049065e-20 kWh
5 × 4.45049065e-20 = 2.225245325e-19 kWh
