How the formula works
Both centijoule and electronvolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in centijoules by 6.241509074e+16 to get electronvolts. To reverse the conversion, multiply a electronvolt value by 1.602176634e-17 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 Electronvolt (eV)?
An electronvolt (eV) is the energy gained by a single electron accelerating through a potential difference of one volt, widely used in atomic and particle physics.
How do I convert centijoules to electronvolts?
Multiply the centijoule value by 6.241509074e+16 to get the equivalent in electronvolts. For example, 5 cJ × 6.241509074e+16 = 3.120755e+17 eV.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 6.241509074e+16 is an exact, non-rounded value.
Can I convert electronvolts back to centijoules?
Yes. Divide the electronvolt value by 6.241509074e+16, or multiply it by 1.602176634e-17, to get centijoules.
