Gigawatt-hour [GWh] to Megawatt-hour [MWh] Converter

Quick Reference

1 Gigawatt-hour (GWh) = 1000 Megawatt-hour (MWh)

1 Megawatt-hour (MWh) = 0.001 Gigawatt-hour (GWh)

How to Convert Gigawatt-hour to Megawatt-hour

1 GWh = 1000 MWh
1 MWh = 0.001 GWh

To convert Gigawatt-hour to Megawatt-hour, multiply the value by 1000. To convert Megawatt-hour back to Gigawatt-hour, divide by 1000.

Example: convert 10 GWh to MWh:
10 GWh = 10 x 1000 = 10000 MWh

↔ Convert Megawatt-hour to Gigawatt-hour

Gigawatt-hour

Definition: A gigawatt-hour (symbol GWh) is a unit of energy equal to one gigawatt (1,000,000,000 watts) of power sustained for one hour. It represents a very large amount of energy.

History/origin: The gigawatt-hour is a derivative of the watt-hour, using the SI prefix 'giga-' to denote a factor of one billion. It became relevant with the development of very large-scale power generation facilities.

Current use: Gigawatt-hours are used to measure the energy output of entire power grids, the energy consumption of large countries or regions, and the total energy production of large renewable energy projects.

Megawatt-hour

Definition: A megawatt-hour (symbol MWh) is a unit of energy equal to one megawatt (1,000,000 watts) of power sustained for one hour. It represents a large amount of energy.

History/origin: The megawatt-hour is a derivative of the watt-hour, using the SI prefix 'mega-' to denote a factor of one million. It was developed to represent energy production and consumption on a larger scale.

Current use: Megawatt-hours are used to measure the energy output of large power plants, the energy consumption of large industrial facilities, and the trading of electricity on wholesale markets.
