How the formula works
Both centijoule and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 0.1 to get decijoules. To reverse the conversion, multiply a decijoule value by 10 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 Decijoule (dJ)?
A decijoule (dJ) is a metric-prefixed unit of energy equal to 10-1 joules, a fraction of a single joule, using the SI deci prefix.
How do I convert centijoules to decijoules?
Multiply the centijoule value by 0.1 to get the equivalent in decijoules. For example, 5 cJ × 0.1 = 0.500000 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.1 is an exact, non-rounded value.
Can I convert decijoules back to centijoules?
Yes. Divide the decijoule value by 0.1, or multiply it by 10, to get centijoules.
