Enter a value to instantly convert between energy units.
1 BTU (IT) = 0.0003 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 = BTU × 0.000293One BTU (IT) equals 0.000293 kilowatt-hours. Since 1 BTU = 1055 J and 1 kWh = 3,600,000 J, the conversion is 1055/3,600,000 = 0.000293 kWh per BTU. This is useful when converting heating values to electrical equivalent.
