1 Kilowatt-Hour = 0.0341 Therm (US)
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
therms = kWh × 0.0341214A therm is 100,000 BTU — the standard unit for natural gas billing in the US. One kilowatt-hour equals about 0.034 therms, meaning a typical home using 800 kWh/month consumes roughly 27 therms. Gas utilities and HVAC engineers frequently convert between these units when sizing equipment or analyzing bills.
