Show the working
  1. 1 MMBtu = 1055055.85262 kJ
  2. 1 × 1055055.85262 = 1055055.85262 kJ

How to convert million btu to kilojoules

1 MMBtu = 1,055,055.85262 kJ, so multiply by 1,055,055.85262 to go from million Btu to kilojoules. Going the other way, 1 kJ = 9.47817120313 × 10⁻⁷ MMBtu.

kJ = MMBtu × 1,055,055.85262
MMBtu = kJ × 9.47817120313

Worked example:

1 MMBtu = 1055055.85262 kJ
5 × 1055055.85262 = 5275279.2631 kJ
