Since one kWh is equal to 3,412 BTU, to convert BTU to kWh, simply divide the number of BTUs by 3,412, according to Think Energy Management. Alternatively, multiply BTUs by 0.000293 or 1/3,412, according to Stovesonline.com. Reverse the calculation to convert kWh to BTU by multiplying the number of kWh by 3,412.
According to the American Physical Society, the BTU or British Thermal Unit is the British equivalent of the calorie. One BTU is a measure of the amount of energy necessary to raise the temperature of 1 pound of water by 1 degree Fahrenheit. A kilowatt-hour or kWh is the standard measurement of electricity use or production. This conversion rate is based on the International Table BTU used by the U.S. Department of Energy.
Converting energy units allows for comparison of energy output and consumptions to various sources of energy. For example, if a stove boiler lists output in BTUs, converting to kWh allows you to understand the output in terms of electricity. Government agencies, such as the Bureau of Land Management, also use these conversions to understand the amount of energy created from coal and natural gas. For example, a short ton of coal can be used to produce 2,000 kWh of electricity or 25,198,000 BTUs.
