How the formula works
Both electronvolt and microjoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-13 to get microjoules. To reverse the conversion, multiply a microjoule value by 6241509074461 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 Microjoule (uJ)?
A microjoule (uJ) is a metric-prefixed unit of energy equal to 10-6 joules, a fraction of a single joule, using the SI micro prefix.
How do I convert electronvolts to microjoules?
Multiply the electronvolt value by 1.602176634e-13 to get the equivalent in microjoules. For example, 5 eV × 1.602176634e-13 = 8.010883e-13 uJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-13 is an exact, non-rounded value.
Can I convert microjoules back to electronvolts?
Yes. Divide the microjoule value by 1.602176634e-13, or multiply it by 6241509074461, to get electronvolts.
