kWh to MWh Calculator
Convert kilowatt-hours to megawatt-hours (and back) — plus watt-hours and gigawatt-hours. A megawatt-hour is 1,000 kilowatt-hours, so MWh = kWh ÷ 1,000. Handy for reading utility reports, solar-farm output, and grid-scale data in the unit your bill uses.
1,000 kWh = 1 MWh · 1,000,000 kWh = 1 GWh. These are energy units — the kWh is what your utility bills; MWh and GWh show up in utility, solar-farm, and grid data.
