1 MMBtu = 293,071.070172 Wh

Show the working
  1. 1 MMBtu = 293071.070172 Wh
  2. 1 × 293071.070172 = 293071.070172 Wh

How to convert million btu to watt-hours

1 MMBtu = 293,071.070172 Wh, so multiply by 293,071.070172 to go from million Btu to watt-hours. Going the other way, 1 Wh = 3.41214163313 × 10⁻⁶ MMBtu.

Wh = MMBtu × 293,071.070172
MMBtu = Wh × 3.41214163313

Worked example:

1 MMBtu = 293071.070172 Wh
5 × 293071.070172 = 1465355.35086 Wh
