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.
Joules (J)
The joule is the SI unit of energy: the work done by a force of one newton over one meter. Lifting a small apple one meter takes about one joule.
