  2. 1 × 1000000 = 1000000 Btu

How to convert million btu to british thermal units

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

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

Worked example:

1 MMBtu = 1000000 Btu
5 × 1000000 = 5000000 Btu
