How the formula works
Both centijoule and ronnajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 1.000000000e-29 to get ronnajoules. To reverse the conversion, multiply a ronnajoule value by 1.000000000e+29 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 Ronnajoule (RJ)?
A ronnajoule (RJ) is a metric-prefixed unit of energy equal to 1027 joules, using the SI ronna prefix.
How do I convert centijoules to ronnajoules?
Multiply the centijoule value by 1.000000000e-29 to get the equivalent in ronnajoules. For example, 5 cJ × 1.000000000e-29 = 5.000000e-29 RJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-29 is an exact, non-rounded value.
Can I convert ronnajoules back to centijoules?
Yes. Divide the ronnajoule value by 1.000000000e-29, or multiply it by 1.000000000e+29, to get centijoules.
