About British Thermal Unit and Kilowatt-hour

The British thermal unit is about 1,055.06 joules — the heat to raise one pound of water by 1 °F. US heating and cooling equipment is rated in BTU per hour. The kilowatt-hour is exactly 3.6 megajoules — the unit on your electricity bill. Household consumption and electric vehicle battery sizes are stated in kilowatt-hours. One British Thermal Unit equals 0.0002930710702 Kilowatt-hour (1 BTU = 0.0002930710702 kWh). British Thermal Unit to Kilowatt-hour conversion comes up most often in air conditioner and furnace ratings in the US and in US natural gas appliance specs, typically when figures need restating for electricity billing.

Precision and Rounding: Energy factors mix exact definitions (1 kWh = 3,600,000 J; 1 cal = 4.184 J thermochemical) with measured conventions (1 BTU ≈ 1,055.056 J). Nutrition and utility bills round to whole units; engineering heat calculations should keep the full factor until the final step.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
