About British thermal unit (IT)
The British thermal unit (IT) is a unit of energy equal to 1,055.05585 joules (1 BTU (IT) = 1,055.05585 J), the SI derived unit of energy.
The British thermal unit (IT) is also equal to 1.05505585 kilojoules (kJ), or 252.164401 calories (thermochemical) (cal), or 0.252164401 kilocalories (thermochemical) (kcal), or 0.5555556 Celsius heat units (IT) (CHU), or 0.29307107 watt hours (Wh) or 0.00029307107 kilowatt hours (kWh).
The British thermal unit is the energy required to increase the temperature of one pound of water by one degree Fahrenheit (0.556 degrees Celsius) at a constant pressure of one atmosphere.
