1 Therm (US) = 29.3001 Kilowatt-Hour
Key Formulas
Kilocalorie → Kilojoule
kJ = kcal × 4.184Kilojoule → Kilocalorie
kcal = kJ × 0.239006Kilowatt-Hour → Joule
J = kWh × 3600000Joule → Kilowatt-Hour
kWh = J × 2.77778e-7Formula
kWh = therms × 29.3001One US therm equals exactly 100,000 BTU, and since 1 kWh = 3412 BTU, a therm converts to 29.3 kWh (100,000 ÷ 3412). This is a key conversion for comparing gas and electric energy — utilities use therms for gas, kilowatt-hours for electricity. Energy auditors and HVAC engineers use this daily.
