How the formula works
Both erg and electronvolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ergs by 624150907446 to get electronvolts. To reverse the conversion, multiply a electronvolt value by 1.602176634e-12 to get back to ergs.
Frequently asked questions
What is Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
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 ergs to electronvolts?
Multiply the erg value by 624150907446 to get the equivalent in electronvolts. For example, 5 erg × 624150907446 = 3.120755e+12 eV.
Is this conversion exact?
