  1. 1 Mcal = 0.00396566683139 MMBtu
  2. 1 × 0.00396566683139 = 0.00396566683139 MMBtu

How to convert megacalories to million btu

1 Mcal = 0.00396566683139 MMBtu, so multiply by 0.00396566683139 to go from megacalories to million Btu. Going the other way, 1 MMBtu = 252.164400722 Mcal.

MMBtu = Mcal × 0.00396566683139
Mcal = MMBtu × 252.164400722

Worked example:

1 Mcal = 0.00396566683139 MMBtu
5 × 0.00396566683139 = 0.019828334157 MMBtu
