British thermal unit
The British thermal unit (BTU or Btu) is a unit of energy used in the power, steam generation, heating and air conditioning industries. Although it is still used 'unofficially' in metric English-speaking countries (such as Canada, the United Kingdom, and sometimes in New Zealand), its use has declined or has been replaced in other parts of the world. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule (J), though it may be used as a measure of agricultural energy production (BTU/kg). In North America, the term 'BTU' is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU 'per hour' (BTU/h, that is, BTU divided by hour) is understood, though this is often confusingly abbreviated to just 'BTU'.

British thermal unit
De British thermal unit (BTU of Btu) is een eenheid van energie die gebruikt wordt in de Verenigde Staten. Ook komt men deze eenheid nog sporadisch tegen in het Verenigd Koninkrijk, in de context van oude koelsystemen en verwarmingssystemen. Buiten die gebieden is de BTU vrijwel geheel vervangen door de joule (J) die voorgeschreven wordt door het SI. De definitie van een BTU is de hoeveelheid warmte die nodig is om de temperatuur van een pond avoirdupois aan water met één graad Fahrenheit te verhogen.
