How the formula works
Both yoctojoule and electronvolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctojoules by 0.000006241509074 to get electronvolts. To reverse the conversion, multiply a electronvolt value by 160217.6634 to get back to yoctojoules.
Frequently asked questions
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.
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 yoctojoules to electronvolts?
Multiply the yoctojoule value by 0.000006241509074 to get the equivalent in electronvolts. For example, 5 yJ × 0.000006241509074 = 0.000031 eV.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.000006241509074 is an exact, non-rounded value.
Can I convert electronvolts back to yoctojoules?
Yes. Divide the electronvolt value by 0.000006241509074, or multiply it by 160217.6634, to get yoctojoules.
