Kilojoules (kJ) to British thermal units (BTU) Conversion
Kilojoules
The kilojoule (kJ) is a unit of energy equal to exactly 1,000 joules. It is the standard unit for expressing food energy in most countries outside the United States, where food labels display energy in both kilojoules and kilocalories (kcal). One kilocalorie equals exactly 4.184 kilojoules. In thermodynamics and chemistry, reaction enthalpies and bond energies are commonly tabulated in kilojoules per mole (kJ/mol).
British thermal units
The British thermal unit (BTU) is a unit of energy approximately equal to 1,055.06 joules, defined as the energy required to raise the temperature of one pound of water by one degree Fahrenheit. It remains the standard unit for heating and cooling capacity in HVAC systems in the United States: air conditioners and furnaces are rated in BTU/hour. A typical residential air conditioner is rated at 5,000–24,000 BTU/h. One BTU equals approximately 0.000293 kWh.
