How the formula works
Both electronvolt and rontojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in electronvolts by 160217663.4 to get rontojoules. To reverse the conversion, multiply a rontojoule value by 6.241509074e-09 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 Rontojoule (rJ)?
A rontojoule (rJ) is a metric-prefixed unit of energy equal to 10-27 joules, a fraction of a single joule, using the SI ronto prefix.
How do I convert electronvolts to rontojoules?
Multiply the electronvolt value by 160217663.4 to get the equivalent in rontojoules. For example, 5 eV × 160217663.4 = 8.010883e+08 rJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 160217663.4 is an exact, non-rounded value.
Can I convert rontojoules back to electronvolts?
Yes. Divide the rontojoule value by 160217663.4, or multiply it by 6.241509074e-09, to get electronvolts.
