1 Kilowatt-Hour = 3412.1416 BTU (IT)
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
BTU = kWh × 3412.14One kilowatt-hour equals 3412 BTU exactly. Since 1 kWh = 3.6 megajoules and 1 BTU = 1.055 kilojoules, dividing 3600 by 1.055 gives 3412.14. This conversion is critical for HVAC professionals comparing electrical heating to furnace BTU ratings, energy auditors analyzing power consumption in thermal terms, and renewable energy planners calculating solar panel output in heating equivalents.
