1 keV = 4.45049065 × 10⁻²⁶ MWh

Show the working
  1. 1 keV = 4.45049065e-26 MWh
  2. 1 × 4.45049065e-26 = 4.45049065e-26 MWh

How to convert kiloelectronvolts to megawatt-hours

1 keV = 4.45049065 × 10⁻²⁶ MWh, so multiply by 4.45049065 to go from kiloelectronvolts to megawatt-hours. Going the other way, 1 MWh = 2.24694326681 × 10²⁵ keV.

MWh = keV × 4.45049065
keV = MWh × 2.24694326681

Worked example:

1 keV = 4.45049065e-26 MWh
5 × 4.45049065e-26 = 2.225245325e-25 MWh
