1 MMBtu = 0.293071070172 MWh

Show the working
  1. 1 MMBtu = 0.293071070172 MWh
  2. 1 × 0.293071070172 = 0.293071070172 MWh

How to convert million btu to megawatt-hours

1 MMBtu = 0.293071070172 MWh, so multiply by 0.293071070172 to go from million Btu to megawatt-hours. Going the other way, 1 MWh = 3.41214163313 MMBtu.

MWh = MMBtu × 0.293071070172
MMBtu = MWh × 3.41214163313

Worked example:

1 MMBtu = 0.293071070172 MWh
5 × 0.293071070172 = 1.46535535086 MWh
