The Btu should not be confused with the Board of Trade Unit (BTU), an obsolete UK synonym for kilowatt hour (1 kW⋅h or 3,412 Btu). The Btu is often used to express the conversion-efficiency of heat into electrical energy in power plants.
British thermal unit (Btu) measures the heat content of fuels or energy sources. One Btu is the amount of heat needed to raise the temperature of one pound of water by 1° Fahrenheit (F). A single Btu is very small in terms of the amount of energy a single household or an entire country uses.
BTU stands for British Thermal Unit, a unit of measurement that shows just how much energy your heating or cooling unit uses to remove heat from your home within an hour.

BTU's are a commonly used specification on heating and cooling systems. But what is BTU? We explain it in simple terms and provide calculators, conversion charts and more.
British thermal unit (BTU), a measure of the quantity of heat, defined since 1956 as approximately equal to 1,055 joules, or 252 gram calories. It was defined formerly as the amount of heat required to raise the temperature of one pound of water 1° F.
BTU, short for British Thermal Unit, is a standardized, basic measurement of energy for all heating and cooling appliances. It is a measure of how much heat (or cooling) can be generated by the appliance from a given amount of fuel.
You can compare the average fuel prices over the winter (October through March) by dividing the average natural gas and heating oil monthly prices per unit by the Btu content of the fuels in million Btu.
