How the formula works
Both centijoule and petajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 1.000000000e-17 to get petajoules. To reverse the conversion, multiply a petajoule value by 1.000000000e+17 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 Petajoule (PJ)?
A petajoule (PJ) is a metric-prefixed unit of energy equal to 1015 joules, using the SI peta prefix.
How do I convert centijoules to petajoules?
Multiply the centijoule value by 1.000000000e-17 to get the equivalent in petajoules. For example, 5 cJ × 1.000000000e-17 = 5.000000e-17 PJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-17 is an exact, non-rounded value.
Can I convert petajoules back to centijoules?
Yes. Divide the petajoule value by 1.000000000e-17, or multiply it by 1.000000000e+17, to get centijoules.
