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