How the formula works
Both centijoule and exajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 1.000000000e-20 to get exajoules. To reverse the conversion, multiply a exajoule value by 1.000000000e+20 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 Exajoule (EJ)?
A exajoule (EJ) is a metric-prefixed unit of energy equal to 1018 joules, using the SI exa prefix.
How do I convert centijoules to exajoules?
Multiply the centijoule value by 1.000000000e-20 to get the equivalent in exajoules. For example, 5 cJ × 1.000000000e-20 = 5.000000e-20 EJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-20 is an exact, non-rounded value.
Can I convert exajoules back to centijoules?
Yes. Divide the exajoule value by 1.000000000e-20, or multiply it by 1.000000000e+20, to get centijoules.
