British Thermal Units to Kilowatt-hours Converter

To convert a measurement in british thermal units to kilowatt-hours, multiply the value by 0.00029307107. The conversion factor comes from the relationship between both units and the joule.

For example, to convert 5 BTU to kilowatt-hours: 5 × 0.00029307107 = 0.001465355351 kWh.

A British thermal unit (BTU) is the energy needed to raise the temperature of one pound of water by one degree Fahrenheit, about 1,055 joules. The BTU arose from imperial heating and steam engineering. It remains the dominant unit for heating, ventilation, and air-conditioning capacity in the United States, where furnaces and air conditioners are rated in BTU.

Common uses of british thermal units include: Air conditioner and furnace ratings; Heating and cooling load calculations; Natural gas and fuel energy content; HVAC system sizing in the US.

A kilowatt-hour equals 1,000 watt-hours, or 3.6 million joules, and is the standard unit for billing electrical energy. The kilowatt-hour became the universal unit of electricity metering because it conveniently expresses household consumption. Running a 1,000-watt appliance for one hour uses exactly one kWh.

Common uses of kilowatt-hours include: Household electricity billing; Electric vehicle battery capacity; Home solar and battery systems; Energy audits and efficiency ratings.
