How the formula works
Both centijoule and attojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 1.000000000e+16 to get attojoules. To reverse the conversion, multiply a attojoule value by 1.000000000e-16 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 Attojoule (aJ)?
A attojoule (aJ) is a metric-prefixed unit of energy equal to 10-18 joules, a fraction of a single joule, using the SI atto prefix.
How do I convert centijoules to attojoules?
Multiply the centijoule value by 1.000000000e+16 to get the equivalent in attojoules. For example, 5 cJ × 1.000000000e+16 = 5.000000e+16 aJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+16 is an exact, non-rounded value.
Can I convert attojoules back to centijoules?
Yes. Divide the attojoule value by 1.000000000e+16, or multiply it by 1.000000000e-16, to get centijoules.
