How the formula works
Both microjoule and centijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microjoules by 0.0001 to get centijoules. To reverse the conversion, multiply a centijoule value by 10000 to get back to microjoules.
Frequently asked questions
What is Microjoule (uJ)?
A microjoule (uJ) is a metric-prefixed unit of energy equal to 10-6 joules, a fraction of a single joule, using the SI micro prefix.
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.
How do I convert microjoules to centijoules?
Multiply the microjoule value by 0.0001 to get the equivalent in centijoules. For example, 5 uJ × 0.0001 = 0.000500 cJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.0001 is an exact, non-rounded value.
Can I convert centijoules back to microjoules?
Yes. Divide the centijoule value by 0.0001, or multiply it by 10000, to get microjoules.
