1 thm = 105.505585262 MJ

Show the working
  1. 1 thm = 105.505585262 MJ
  2. 1 × 105.505585262 = 105.505585262 MJ

How to convert therms to megajoules

1 thm = 105.505585262 MJ, so multiply by 105.505585262 to go from therms (100,000 Btu) to megajoules. Going the other way, 1 MJ = 0.00947817120313 thm.

MJ = thm × 105.505585262
thm = MJ × 0.00947817120313

Worked example:

1 thm = 105.505585262 MJ
5 × 105.505585262 = 527.52792631 MJ
