Gigawatt-hour [GWh] to Joule [J] Converter

Quick Reference

1 Gigawatt-hour (GWh) = 3.6000e+12 Joule (J)

1 Joule (J) = 2.7778e-13 Gigawatt-hour (GWh)

How to Convert Gigawatt-hour to Joule

1 GWh = 3.6000e+12 J
1 J = 2.7778e-13 GWh

To convert Gigawatt-hour to Joule, multiply the value by 3.6000e+12. To convert Joule back to Gigawatt-hour, divide by 3.6000e+12.

Example: convert 10 GWh to J:
10 GWh = 10 x 3.6000e+12 = 3.6000e+13 J

↔ Convert Joule 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.

Joule

Definition: The joule (symbol: J) is the SI derived unit of energy. It is defined as the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).

History/origin: Named after James Prescott Joule, an English physicist. Joule experimentally determined the mechanical equivalent of heat.

Current use: Used universally in science and engineering to quantify energy, work, and heat. Examples include kinetic energy, potential energy, and heat content of materials.
