How the formula works
Both electronvolt and nanojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-10 to get nanojoules. To reverse the conversion, multiply a nanojoule value by 6241509074 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 Nanojoule (nJ)?
A nanojoule (nJ) is a metric-prefixed unit of energy equal to 10-9 joules, a fraction of a single joule, using the SI nano prefix.
How do I convert electronvolts to nanojoules?
Multiply the electronvolt value by 1.602176634e-10 to get the equivalent in nanojoules. For example, 5 eV × 1.602176634e-10 = 8.010883e-10 nJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-10 is an exact, non-rounded value.
Can I convert nanojoules back to electronvolts?
Yes. Divide the nanojoule value by 1.602176634e-10, or multiply it by 6241509074, to get electronvolts.
