  1. 1 Btu = 1e-6 MMBtu
  2. 1 × 1e-6 = 1e-6 MMBtu

How to convert british thermal units to million btu

1 Btu = 1 × 10⁻⁶ MMBtu, so multiply by 1 to go from British thermal units (IT) to million Btu. Going the other way, 1 MMBtu = 1,000,000 Btu.

MMBtu = Btu × 1
Btu = MMBtu × 1,000,000

Worked example:

1 Btu = 1e-6 MMBtu
5 × 1e-6 = 5e-6 MMBtu
