About these units

Short background on the units used in this conversion.

British Thermal Unit (IT) (Btu (IT))

The British thermal unit (IT) is 1,055.05585262 joules — the heat to raise one pound of water by 1°F (International Table).

BTU rates HVAC heating and cooling capacity, natural-gas appliances, and US energy consumption.

Joule (J)

The joule is the SI unit of energy — the work done when one newton moves an object one meter.

Joules quantify electricity bills (as kWh), food energy (as kcal), and scientific energy transfers.
