How the formula works
Both electronvolt and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-12 to get ergs. To reverse the conversion, multiply a erg value by 624150907446 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 Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
How do I convert electronvolts to ergs?
Multiply the electronvolt value by 1.602176634e-12 to get the equivalent in ergs. For example, 5 eV × 1.602176634e-12 = 8.010883e-12 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-12 is an exact, non-rounded value.
Can I convert ergs back to electronvolts?
Yes. Divide the erg value by 1.602176634e-12, or multiply it by 624150907446, to get electronvolts.
