Conversion Formula
MWh = kWh × 0.001
About Kilowatt-Hours
A kilowatt-hour (kWh) is the energy consumed by 1 kW for one hour - exactly 3,600,000 J = 3.6 MJ. All domestic electricity meters bill in kWh. Appliance benchmarks: fridge 180-250 kWh/year; washing machine 0.5-2.0 kWh/cycle; air conditioner 1-3 kWh/h. EVs consume 13-25 kWh/100 km; the Lucid Air achieves ~15.9 kWh/100 km (WLTP). Producing 1 tonne of primary aluminium requires ~13,000-15,000 kWh. Global electricity generation is ~29,165 TWh ≈ 2.9 × 10¹³ kWh/year. 1 kWh = 3.6 MJ = 3,412.1 BTU = 859.85 kcal.
About Megawatt-Hours
A megawatt-hour (MWh) is the energy from 1 MW for one hour - exactly 3.6 GJ. It is the standard unit for wholesale electricity trading. Power purchase agreements (PPAs) specify capacity and price in $/MWh or €/MWh. A 5 MW wind turbine at full capacity generates 5 MWh/h. Primary aluminium smelting consumes 13-15 MWh per tonne. The Moss Landing battery (California) stores 3,287 MWh. The daily output of a 1 GW nuclear plant at 90% capacity factor is ~21,600 MWh. 1 MWh = 3.6 GJ = 3,412,141 BTU = 1,000 kWh.
