<onlyinclude>'''British Thermal Units''', or BTUs, are a unit of [[energy]]. It is the amount of energy required to heat a pound of water by one degree [[Fahrenheit]] at one [[atm]].</onlyinclude>

The BTU is defined as 251.9958 [[calorie]]s, and due to the calorie having many different accepted values, so does the BTU. These different values of the BTU include:<ref>American Physical Society. ''Energy Units'' [Online]. Available: http://www.aps.org/policy/reports/popa-reports/energy/units.cfm</ref>

| thermochemical Btu || 1 Btu = 1054.35 J
|-
| 59 °F (15 °C) Btu || 1 Btu = 1054.80 J
|-
|International Table Btu || 1 Btu = 1055.06 J
|-
|mean Btu || 1 Btu = 1055.87 J

The International Table BTU is the value that is most commonly accepted in most modern energy publications,<ref>U.S. Department of Energy, ''Annual Energy Review 1995'', Energy Information Administration Report DOE/EIA-0384(95) (Washington, D.C.: U.S. DOE, 1996).</ref> so this will be the value being used whenever the BTU is referred to anywhere in this website.

BTU per hour ([[BTU/hr]]) is a measurement of [[power]], and is more commonly used than BTU. Most house furnaces are rated in BTU/hr.
