About BTUs and joules
BTU (BTU)
The International Table BTU is exactly 1,055.05585262 joules. It is used for heating, cooling and fuel energy content, mainly in the US.
Joule (J)
The joule is the SI unit of energy and work: one newton-meter. It is used in physics, engineering and electrical energy ratings.
Both are units of energy; the base unit used internally is J.
Notes
- Calorie = thermochemical calorie (4.184 J); kilocalorie = 1000 cal (the food “Calorie”).
- BTU = International Table BTU (1055.05585262 J). Other BTU definitions (thermochemical, 39 °F, etc.) differ slightly and are not included.
- Energy is not power: a kilowatt-hour is an amount of energy, a kilowatt is a rate.
