About the units
Kilowatt-hour (kWh)
A kilowatt-hour is the energy used by a 1,000-watt device in one hour, exactly 3.6 million joules. It is the unit electricity is billed in.
British thermal unit (BTU)
One BTU (International Table) is about 1,055 joules, the heat needed to raise one pound of water by one degree Fahrenheit. It is used to rate air conditioners and furnaces.
Frequently asked questions
How do I convert kilowatt-hours to British thermal units?
Multiply the number of kilowatt-hours by 3,412.141633. For example, 10 kilowatt-hours × 3,412.141633 = 34,121.41633 British thermal units.
How many British thermal units are in one kilowatt-hour?
There are 3,412.141633 British thermal units in one kilowatt-hour.
How many kilowatt-hours are in one British thermal unit?
There are 0.0002930711 kilowatt-hours in one British thermal unit.
How many kWh does a 12,000 BTU/h air conditioner use?
A 12,000 BTU/h air conditioner removes about 3.52 kWh of heat per hour. The electricity it uses is lower, typically 1 to 1.5 kWh per hour, because modern units move more heat than the energy they consume.
Can I convert other energy units with this tool?
Yes. Use the From and To drop-downs in the converter to choose any energy unit, or press the swap button to reverse the conversion. All calculations use internationally defined conversion factors.
