How the formula works
Both gigajoule and centijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigajoules by 100000000000 to get centijoules. To reverse the conversion, multiply a centijoule value by 1.000000000e-11 to get back to gigajoules.
Frequently asked questions
What is Gigajoule (GJ)?
A gigajoule (GJ) is a metric-prefixed unit of energy equal to 109 joules, using the SI giga prefix.
What is Centijoule (cJ)?
A centijoule (cJ) is a metric-prefixed unit of energy equal to 10-2 joules, a fraction of a single joule, using the SI centi prefix.
How do I convert gigajoules to centijoules?
Multiply the gigajoule value by 100000000000 to get the equivalent in centijoules. For example, 5 GJ × 100000000000 = 5.000000e+11 cJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 100000000000 is an exact, non-rounded value.
Can I convert centijoules back to gigajoules?
Yes. Divide the centijoule value by 100000000000, or multiply it by 1.000000000e-11, to get gigajoules.
