1 thm = 29.3071070172 kWh

Show the working
  1. 1 thm = 29.3071070172 kWh
  2. 1 × 29.3071070172 = 29.3071070172 kWh

How to convert therms to kilowatt-hours

1 thm = 29.3071070172 kWh, so multiply by 29.3071070172 to go from therms (100,000 Btu) to kilowatt-hours. Going the other way, 1 kWh = 0.0341214163313 thm.

kWh = thm × 29.3071070172
thm = kWh × 0.0341214163313

Worked example:

1 thm = 29.3071070172 kWh
5 × 29.3071070172 = 146.535535086 kWh
