1 Gigawatt-hour equals exactly
1.000 MWh
The Gigawatt-hour (GWh) and the Megawatt-hour (MWh) are both units of electrical energy used for very large quantities, typical of the production of entire power plants or the energy consumption of cities or regions. Since 'giga' means one billion and 'mega' means one million, one GWh contains exactly 1,000 MWh.
To convert a measurement from GWh to MWh, simply multiply the value by 1,000:
To convert from MWh to GWh, perform the inverse operation, dividing by 1,000:
These units are the standard in national energy production reports, consumption statistics for entire cities or regions, and energy balances of large facilities such as power plants, wind farms, or large-scale photovoltaic installations.
