How the formula works
Both electronvolt and zeptojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 160.2176634 to get zeptojoules. To reverse the conversion, multiply a zeptojoule value by 0.006241509074 to get back to electronvolts.
Frequently asked questions
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.
What is Zeptojoule (zJ)?
A zeptojoule (zJ) is a metric-prefixed unit of energy equal to 10-21 joules, a fraction of a single joule, using the SI zepto prefix.
How do I convert electronvolts to zeptojoules?
Multiply the electronvolt value by 160.2176634 to get the equivalent in zeptojoules. For example, 5 eV × 160.2176634 = 801.088317 zJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 160.2176634 is an exact, non-rounded value.
Can I convert zeptojoules back to electronvolts?
Yes. Divide the zeptojoule value by 160.2176634, or multiply it by 0.006241509074, to get electronvolts.
