How the formula works
Both electronvolt and yoctojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 160217.6634 to get yoctojoules. To reverse the conversion, multiply a yoctojoule value by 0.000006241509074 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 Yoctojoule (yJ)?
A yoctojoule (yJ) is a metric-prefixed unit of energy equal to 10-24 joules, a fraction of a single joule, using the SI yocto prefix.
How do I convert electronvolts to yoctojoules?
Multiply the electronvolt value by 160217.6634 to get the equivalent in yoctojoules. For example, 5 eV × 160217.6634 = 801088.317000 yJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 160217.6634 is an exact, non-rounded value.
Can I convert yoctojoules back to electronvolts?
Yes. Divide the yoctojoule value by 160217.6634, or multiply it by 0.000006241509074, to get electronvolts.
