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 — the unit on your electricity bill. Household consumption and electric vehicle battery sizes are stated in kilowatt-hours. One Megawatt-hour equals 1000 Kilowatt-hour (1 MWh = 1000 kWh). Megawatt-hour to Kilowatt-hour conversion comes up most often in wholesale electricity markets and in grid-scale storage capacity, 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).

Worked Example

15 Megawatt-hour equals 15000 Kilowatt-hour.

15 MWh × 1000 = 15000 kWh
