Kilojoules to gigawatt-hour Conversion
1 kilojoules (kJ) is equal to 0.0000000002777777778 gigawatt-hour (GW⋅hr).
1 kJ = 0.0000000002777777778 GW⋅hr
or
1 GW⋅hr = 3600000000 kJ
Formula
To convert a energy from kilojoules (kJ) to gigawatt-hour (GW⋅hr), divide the energy in kilojoules by 3600000000
e(GW⋅hr) = e(kJ) / 3600000000
Examples:
Convert 500 kilojoules to gigawatt-hour:
e(GW⋅hr) = 500kJ / 3600000000 = 0.0000001388888889 GW⋅hr

Frequently asked questions
How do I convert kilojoules to gigawatt-hour?
Divide the value in kilojoules by 3600000000 to get the result in gigawatt-hour. For example, 5 kJ ÷ 3600000000 = 1.389e-9 GW⋅hr.
How many gigawatt-hour are in 1 kilojoules?
1 kilojoules (kJ) is equal to 2.78e-10 gigawatt-hour (GW⋅hr).
How do I convert gigawatt-hour back to kilojoules?
Use the inverse operation: multiply the value in gigawatt-hour by 3600000000 to get the result in kilojoules.
How accurate is the kilojoules to gigawatt-hour conversion?
The converter multiplies by the conversion factor 3600000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
