About these units
Joule
The joule is the SI unit of energy, used universally in physics and international engineering. It is the coherent unit derived from base SI quantities (kg·m²/s²).
British Thermal Unit
The BTU (British Thermal Unit) is the heat required to raise one pound of water by 1°F. Despite its name, it is now primarily used in US HVAC, power generation, and energy policy rather than in the UK.
