How the formula works
Both centijoule and zeptojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 1.000000000e+19 to get zeptojoules. To reverse the conversion, multiply a zeptojoule value by 1.000000000e-19 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 Zeptojoule (zJ)?
A zeptojoule (zJ) is a metric-prefixed unit of energy equal to 10-21 joules, a fraction of a single joule, using the SI zepto prefix.
How do I convert centijoules to zeptojoules?
Multiply the centijoule value by 1.000000000e+19 to get the equivalent in zeptojoules. For example, 5 cJ × 1.000000000e+19 = 5.000000e+19 zJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+19 is an exact, non-rounded value.
Can I convert zeptojoules back to centijoules?
Yes. Divide the zeptojoule value by 1.000000000e+19, or multiply it by 1.000000000e-19, to get centijoules.
