Show the working
  1. 1 MJ = 0.00947817120313 thm
  2. 1 × 0.00947817120313 = 0.00947817120313 thm

How to convert megajoules to therms

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

thm = MJ × 0.00947817120313
MJ = thm × 105.505585262

Worked example:

1 MJ = 0.00947817120313 thm
5 × 0.00947817120313 = 0.0473908560157 thm
