How the formula works
Both ronnajoule and electronvolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ronnajoules by 6.241509074e+45 to get electronvolts. To reverse the conversion, multiply a electronvolt value by 1.602176634e-46 to get back to ronnajoules.
Frequently asked questions
What is Ronnajoule (RJ)?
A ronnajoule (RJ) is a metric-prefixed unit of energy equal to 1027 joules, using the SI ronna prefix.
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 ronnajoules to electronvolts?
Multiply the ronnajoule value by 6.241509074e+45 to get the equivalent in electronvolts. For example, 5 RJ × 6.241509074e+45 = 3.120755e+46 eV.
Is this conversion exact?
