How the formula works
Both centijoule and quectojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 1.000000000e+28 to get quectojoules. To reverse the conversion, multiply a quectojoule value by 1.000000000e-28 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 Quectojoule (qJ)?
A quectojoule (qJ) is a metric-prefixed unit of energy equal to 10-30 joules, a fraction of a single joule, using the SI quecto prefix.
How do I convert centijoules to quectojoules?
Multiply the centijoule value by 1.000000000e+28 to get the equivalent in quectojoules. For example, 5 cJ × 1.000000000e+28 = 5.000000e+28 qJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+28 is an exact, non-rounded value.
Can I convert quectojoules back to centijoules?
Yes. Divide the quectojoule value by 1.000000000e+28, or multiply it by 1.000000000e-28, to get centijoules.
