MWh to kWh Calculator
Convert megawatt-hours to kilowatt-hours (and back) — plus watt-hours and gigawatt-hours. These are all units of energy; a megawatt-hour is simply 1,000 kilowatt-hours. Enter a value in any unit to see the rest.
1 MWh = 1,000 kWh · 1 kWh = 1,000 Wh · 1 GWh = 1,000,000 kWh. These are energy units (power over time) — the kWh is what your utility bills.

MWh to kWh conversion table
MWh × 1,000 = kWh. The last two columns put each figure in household terms, using the US average home (863 kWh/month) and the US average residential rate (16.5¢/kWh), both EIA, 2024 annual avg.

MWh, kWh and “units” of electricity
A “unit” of electricity is one kilowatt-hour, the unit your meter counts. That makes the conversion identical: 1 MWh = 1,000 units, 1.5 MWh = 1,500 units, 2.2 MWh = 2,200 units. Megawatt-hours turn up on utility reports, solar farm output figures, and commercial bills. Kilowatt-hours (units) are what a household is billed in.
- 1 GWh = 1,000 MWh = 1,000,000 kWh
- 1 MWh = 1,000 kWh = 1,000,000 Wh
- 1 kWh = 1 unit = 0.001 MWh
