About Megawatt-hour and British Thermal Unit
The megawatt-hour is 1,000 kilowatt-hours. Power plants, grid storage, and wholesale electricity markets trade in megawatt-hours. 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. One Megawatt-hour equals 3412141.633 British Thermal Unit (1 MWh = 3412141.633 BTU). Megawatt-hour to British Thermal Unit conversion comes up most often in wholesale electricity markets and in grid-scale storage capacity, typically when figures need restating for air conditioner and furnace ratings in the US.
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).
