About these units
British Thermal Units (BTU)
A British thermal unit is the energy needed to raise one pound of water by one degree Fahrenheit, about 1,055 joules. Heating and air-conditioning capacities are rated in BTU per hour.
Kilojoules (kJ)
A kilojoule is 1,000 joules. Food energy is labelled in kilojoules in many countries; 1 kJ is about 0.239 kilocalories.
