Kilojoules to gigajoule Conversion
1 kilojoules (kJ) is equal to 0.000001 gigajoule (GJ).
1 kJ = 0.000001 GJ
or
1 GJ = 1000000 kJ
Formula
To convert a energy from kilojoules (kJ) to gigajoule (GJ), divide the energy in kilojoules by 1000000
e(GJ) = e(kJ) / 1000000
Examples:
Convert 1 kilojoules to gigajoule:
e(GJ) = 1kJ / 1000000 = 0.000001 GJ

Frequently asked questions
How do I convert kilojoules to gigajoule?
Divide the value in kilojoules by 1000000 to get the result in gigajoule. For example, 5 kJ ÷ 1000000 = 5e-6 GJ.
How many gigajoule are in 1 kilojoules?
1 kilojoules (kJ) is equal to 1e-6 gigajoule (GJ).
How do I convert gigajoule back to kilojoules?
Use the inverse operation: multiply the value in gigajoule by 1000000 to get the result in kilojoules.
How accurate is the kilojoules to gigajoule conversion?
The converter multiplies by the conversion factor 1000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
