How to convert joules to million btu

1 J = 9.47817120313 × 10⁻¹⁰ MMBtu, so multiply by 9.47817120313 to go from joules (watt-seconds) to million Btu. Going the other way, 1 MMBtu = 1,055,055,852.62 J.

MMBtu = J × 9.47817120313
J = MMBtu × 1,055,055,852.62

Worked example:

1 J = 9.47817120313e-10 MMBtu
5 × 9.47817120313e-10 = 4.73908560157e-9 MMBtu
