About the units
British thermal unit (BTU)
The International Table BTU, 1,055.05585262 J — roughly the energy to heat one pound of water by 1 °F. Furnace and AC capacities are rated in BTU (per hour). One British thermal unit equals 1,055.055853 joules (J).
Kilowatt-hour (kWh)
Exactly 3.6 MJ. The unit on electricity bills; running a 1,000 W heater for an hour uses 1 kWh. One kilowatt-hour equals 3,600,000 joules (J).
