Gigawatt-hour [GWh] to Kilowatt-hour [kWh] Converter

Quick Reference

1 Gigawatt-hour (GWh) = 1000000 Kilowatt-hour (kWh)

1 Kilowatt-hour (kWh) = 1.0000e-6 Gigawatt-hour (GWh)

How to Convert Gigawatt-hour to Kilowatt-hour

1 GWh = 1000000 kWh
1 kWh = 1.0000e-6 GWh

To convert Gigawatt-hour to Kilowatt-hour, multiply the value by 1000000. To convert Kilowatt-hour back to Gigawatt-hour, divide by 1000000.

Example: convert 10 GWh to kWh:
10 GWh = 10 x 1000000 = 10000000 kWh

↔ Convert Kilowatt-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.

Kilowatt-hour

Definition: A kilowatt-hour (symbol kWh) is a unit of energy equal to one kilowatt (1,000 watts) of power sustained for one hour. It is a standard unit for measuring electrical energy consumption.

History/origin: The kilowatt-hour became widely adopted with the expansion of electrical grids and the need for a practical unit to measure household and industrial energy usage.

Current use: Kilowatt-hours are the standard unit used by utility companies to bill consumers for electricity usage. It's also used to specify the energy output of power plants and the energy consumption of large appliances.
