About British Thermal Unit and Megawatt-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 megawatt-hour is 1,000 kilowatt-hours. Power plants, grid storage, and wholesale electricity markets trade in megawatt-hours. One British Thermal Unit equals 2.930711e-7 Megawatt-hours (1 BTU = 2.930711e-7 MWh). British Thermal Unit is used in air conditioner and furnace ratings in the US and in US natural gas appliance specs. Megawatt-hour is used in wholesale electricity markets.

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).
