Joule [J] to Gigawatt-hour [GWh] Converter
Quick Reference
1 Joule (J) = 2.7778e-13 Gigawatt-hour (GWh)
1 Gigawatt-hour (GWh) = 3.6000e+12 Joule (J)
How to Convert Joule to Gigawatt-hour
1 J = 2.7778e-13 GWh
1 GWh = 3.6000e+12 J
To convert Joule to Gigawatt-hour, divide the value by 3.6000e+12 (equivalently, multiply by 2.7778e-13). To convert Gigawatt-hour back to Joule, multiply by 3.6000e+12.
Example: convert 10 J to GWh:
10 J = 10 x 2.7778e-13 = 2.7778e-12 GWh
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.
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.
