1 MMBtu = 1.05505585262 GJ

Show the working
  1. 1 MMBtu = 1.05505585262 GJ
  2. 1 × 1.05505585262 = 1.05505585262 GJ

How to convert million btu to gigajoules

1 MMBtu = 1.05505585262 GJ, so multiply by 1.05505585262 to go from million Btu to gigajoules. Going the other way, 1 GJ = 0.947817120313 MMBtu.

GJ = MMBtu × 1.05505585262
MMBtu = GJ × 0.947817120313

Worked example:

1 MMBtu = 1.05505585262 GJ
5 × 1.05505585262 = 5.2752792631 GJ
