BTU to kWh Calculator
Convert BTU to kilowatt-hours (and back) — plus therms and MMBtu. These are all units of energy: 1 kWh equals 3,412 BTU. Handy for comparing gas and electric energy use, or sizing how much electricity it takes to replace a fuel.
Energy units: 1 kWh = 3,412 BTU · 1 therm = 100,000 BTU · 1 MMBtu = 1 million BTU. (For heating/cooling power, use the BTU to kW converter.)
