1 MMBtu = 252,164,400.722 cal

Show the working
  1. 1 MMBtu = 252164400.722 cal
  2. 1 × 252164400.722 = 252164400.722 cal

How to convert million btu to calories

1 MMBtu = 252,164,400.722 cal, so multiply by 252,164,400.722 to go from million Btu to calories (thermochemical). Going the other way, 1 cal = 3.96566683139 × 10⁻⁹ MMBtu.

cal = MMBtu × 252,164,400.722
MMBtu = cal × 3.96566683139

Worked example:

1 MMBtu = 252164400.722 cal
5 × 252164400.722 = 1260822003.61 cal
