1 GJ = 0.947817120313 MMBtu

Show the working
  1. 1 GJ = 0.947817120313 MMBtu
  2. 1 × 0.947817120313 = 0.947817120313 MMBtu

How to convert gigajoules to million btu

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

MMBtu = GJ × 0.947817120313
GJ = MMBtu × 1.05505585262

Worked example:

1 GJ = 0.947817120313 MMBtu
5 × 0.947817120313 = 4.73908560157 MMBtu
