1 Wh = 3.41214163313 × 10⁻⁶ MMBtu

Show the working
  1. 1 Wh = 3.41214163313e-6 MMBtu
  2. 1 × 3.41214163313e-6 = 3.41214163313e-6 MMBtu

How to convert watt-hours to million btu

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

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

Worked example:

1 Wh = 3.41214163313e-6 MMBtu
5 × 3.41214163313e-6 = 1.70607081656e-5 MMBtu
