How many BTUs does one kilowatt hour equate to?

One kilowatt hour (kWh) is equivalent to 3,412 British Thermal Units (BTUs). This conversion is based on the relationship that defines energy in both units. A kilowatt hour represents the energy consumed when using a power of one kilowatt for one hour, which can be converted into BTUs, a unit commonly used to measure heat energy.

To understand why 3,412 BTU is the correct answer, it is essential to recognize that this figure is derived from the conversion factor: 1 kWh equals approximately 3.412 BTUs. This value comes from the definition of the kilowatt in relation to the Joule, as well as the specific heat capacity energies involved in heating. Therefore, when calculating energy consumption or conversion between electrical energy (kWh) and thermal energy (BTU), this conversion factor is crucial for accurate calculations in utility services and energy management contexts.
