1 thm = 25.2164400722 Mcal

Show the working
  1. 1 thm = 25.2164400722 Mcal
  2. 1 × 25.2164400722 = 25.2164400722 Mcal

How to convert therms to megacalories

1 thm = 25.2164400722 Mcal, so multiply by 25.2164400722 to go from therms (100,000 Btu) to megacalories. Going the other way, 1 Mcal = 0.0396566683139 thm.

Mcal = thm × 25.2164400722
thm = Mcal × 0.0396566683139

Worked example:

1 thm = 25.2164400722 Mcal
5 × 25.2164400722 = 126.082200361 Mcal
