How the formula works
Both electronvolt and ronnajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 1.602176634e-46 to get ronnajoules. To reverse the conversion, multiply a ronnajoule value by 6.241509074e+45 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 Ronnajoule (RJ)?
A ronnajoule (RJ) is a metric-prefixed unit of energy equal to 1027 joules, using the SI ronna prefix.
How do I convert electronvolts to ronnajoules?
Multiply the electronvolt value by 1.602176634e-46 to get the equivalent in ronnajoules. For example, 5 eV × 1.602176634e-46 = 8.010883e-46 RJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.602176634e-46 is an exact, non-rounded value.
Can I convert ronnajoules back to electronvolts?
Yes. Divide the ronnajoule value by 1.602176634e-46, or multiply it by 6.241509074e+45, to get electronvolts.
