Kilojoule [kJ] to Gigawatt-hour [GWh] Converter

Quick Reference

1 Kilojoule (kJ) = 2.7778e-10 Gigawatt-hour (GWh)

1 Gigawatt-hour (GWh) = 3600000000 Kilojoule (kJ)

How to Convert Kilojoule to Gigawatt-hour

1 kJ = 2.7778e-10 GWh
1 GWh = 3600000000 kJ

To convert Kilojoule to Gigawatt-hour, divide the value by 3600000000 (equivalently, multiply by 2.7778e-10). To convert Gigawatt-hour back to Kilojoule, multiply by 3600000000.

Example: convert 10 kJ to GWh:
10 kJ = 10 x 2.7778e-10 = 2.7778e-9 GWh

↔ Convert Gigawatt-hour to Kilojoule

Kilojoule

Definition: A kilojoule (symbol: kJ) is equal to 1000 joules. It's a unit of energy.

History/origin: Based on the joule, using the SI prefix 'kilo-' to denote a factor of one thousand.

Current use: Commonly used to express the energy content of food, fuels, and other substances when the joule would be impractically small. Also used in thermodynamics and other areas of physics and engineering.

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.
