Gigawatt-hour to joules Conversion
1 gigawatt-hour (GW⋅hr) is equal to 3600000000000 joules (joule).
1 GW⋅hr = 3600000000000 joule
or
1 joule = 0.0000000000002777777778 GW⋅hr
Formula
To convert a energy from gigawatt-hour (GW⋅hr) to joules (joule), multiply the energy in gigawatt-hour by 3600000000000
e(joule) = e(GW⋅hr) × 3600000000000
Examples:
Convert 100 gigawatt-hour to joules:
e(joule) = 100GW⋅hr × 3600000000000 = 360000000000000 joule

Frequently asked questions
How do I convert gigawatt-hour to joules?
Multiply the value in gigawatt-hour by 3600000000000 to get the result in joules. For example, 5 GW⋅hr × 3600000000000 = 1.8e13 joule.
How many joules are in 1 gigawatt-hour?
1 gigawatt-hour (GW⋅hr) is equal to 3.6e12 joules (joule).
How do I convert joules back to gigawatt-hour?
Use the inverse operation: divide the value in joules by 3600000000000 to get the result in gigawatt-hour.
How accurate is the gigawatt-hour to joules conversion?
The converter multiplies by the conversion factor 3600000000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
