About These Units
British Thermal Unit (BTU)
A British Thermal Unit (BTU) is the energy needed to raise 1 pound of water by 1°F, equal to approximately 1,055 joules. BTUs measure heating/cooling capacity (AC units: 5,000-25,000 BTU), fuel energy content, and HVAC systems. One BTU equals 252 calories.
Joule (J)
The joule (J) is the SI unit of energy equal to one watt-second or one newton-meter. Joules measure work, heat, and electrical energy. One joule equals approximately 0.239 calories. Lifting a 100g apple one meter requires about 1 joule. Named after physicist James Prescott Joule.
