How to Convert Gigawatt-hour to Watt-hourWatt-hour

1 GWh = 1000000000 Wh
1 Wh = 1e-9 GWh

Example: convert 9 GWh to Wh:
9 GWh = 9 x 1000000000 = 9000000000 Wh

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.

Watt-hour

Definition: A watt-hour (symbol Wh) is a unit of energy equal to one watt of power sustained for one hour. It is commonly used to measure electrical energy consumption.

History/origin: The watt-hour is derived from the watt, the SI unit of power, and the hour, a unit of time. It was developed alongside the increasing use of electricity in the late 19th and early 20th centuries.

Current use: Watt-hours are commonly used to measure the energy capacity of batteries, the energy consumption of household appliances, and the amount of electricity generated or consumed by power plants and consumers.
