About Megawatt-hour and Kilowatt-hour
The megawatt-hour is 1,000 kilowatt-hours. Power plants, grid storage, and wholesale electricity markets trade in megawatt-hours. The kilowatt-hour is exactly 3.6 megajoules. It is the unit on your electricity bill. Household consumption and electric vehicle battery sizes are stated in kilowatt-hours. One Megawatt-hour equals 1000 Kilowatt-hours (1 MWh = 1000 kWh). Megawatt-hour is used in wholesale electricity markets and in grid-scale storage capacity. Kilowatt-hour is used in 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).
