How the formula works
Both centijoule and microjoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 10000 to get microjoules. To reverse the conversion, multiply a microjoule value by 0.0001 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 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.
How do I convert centijoules to microjoules?
Multiply the centijoule value by 10000 to get the equivalent in microjoules. For example, 5 cJ × 10000 = 50000 uJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 10000 is an exact, non-rounded value.
Can I convert microjoules back to centijoules?
Yes. Divide the microjoule value by 10000, or multiply it by 0.0001, to get centijoules.
