dcterms:description

The British thermal unit (BTU or Btu) is a traditional unit of energy equal to about 1 055.05585 joules. It is approximately the amount of energy needed to heat 1 pound (0.454 kg) of water from \(39 \,^{\circ}{\rm F}\) (\(3.9 \,^{\circ}{\rm C}\)) to \(40 \,^{\circ}{\rm F}\) (\(4.4 \,^{\circ}{\rm C}\)). The unit is most often used in the power, steam generation, heating and air conditioning industries. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule, though it may be used as a measure of agricultural energy production (BTU/kg).
