1 MMBtu = 1,055.05585262 MJ

Show the working
  1. 1 MMBtu = 1055.05585262 MJ
  2. 1 × 1055.05585262 = 1055.05585262 MJ

How to convert million btu to megajoules

1 MMBtu = 1,055.05585262 MJ, so multiply by 1,055.05585262 to go from million Btu to megajoules. Going the other way, 1 MJ = 0.000947817120313 MMBtu.

MJ = MMBtu × 1,055.05585262
MMBtu = MJ × 0.000947817120313

Worked example:

1 MMBtu = 1055.05585262 MJ
5 × 1055.05585262 = 5275.2792631 MJ
