What is British thermal unit (59 F)?

The British thermal unit (59 °F) is a unit of energy equal to 1,054.804 joules (1 BTU = 1,054.804 J), the SI derived unit of energy. It is also equal to 1.054804 kilojoules (kJ), or 252.104206501 calories (thermochemical) (cal), or 0.252104206501 kilocalories (thermochemical) (kcal), or 0.5554229388 Celsius heat units (IT) (CHU), or 0.2930011111 watt hours (Wh) or 2.930011111x10-4 kilowatt hours (kWh).

The British thermal unit (BTU) is the energy required to increase the temperature of one pound of water by one degree Fahrenheit (or 0.556 degrees Celsius) at a constant pressure of one atmosphere.

The British thermal unit definition varies as follows:

  • The British thermal unit (IT) (BTU) is equal to 1,055.05585262 joules (J)
  • The British thermal unit (ISO) (BTU) is equal to 1,055.056 joules (J)
  • The British thermal unit (thermochemical) (BTU) is equal to about 1,054.35026444 joules (J)
  • The British thermal unit (mean) (BTU) is equal to about 1,055.87 joules (J)
  • The British thermal unit (39 °F) (BTU) is equal to about 1,059.67 joules (J)
  • The British thermal unit (59 °F) (BTU) is equal to 1,054.804 joules (J)
  • The British thermal unit (60 °F) (BTU) is equal to about 1,054.68 joules (J)
  • The British thermal unit (63 °F) (BTU) is equal to about 1,054.6 joules (J)

The most common BTU multiples are:

  • One thousand British thermal units (MBTU, MBtu, e3BTU, BTUE3), equal to 1,000 BTU
  • One million British thermal units (MMBTU, MMBtu, e6BTU, BTUE6), equal to 1,000,000 BTU
  • One therm, equal to 100,000 BTU
  • One quad (energy) (or quadrillion BTU), equal to 1015 BTU

The BTU is commonly used in the power generation, steam generation, heating and air conditioning industries. Usually, the BTU-IT is used in the European Union while the BTU-59 °F is used in the United States.
