How the formula works
Both centijoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 100000 to get ergs. To reverse the conversion, multiply a erg value by 0.00001 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 Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
How do I convert centijoules to ergs?
Multiply the centijoule value by 100000 to get the equivalent in ergs. For example, 5 cJ × 100000 = 500000 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 100000 is an exact, non-rounded value.
Can I convert ergs back to centijoules?
Yes. Divide the erg value by 100000, or multiply it by 0.00001, to get centijoules.
