Tool guide
This guide explains the exact relationship used by Rydberg to Electronvolt Converter, when the conversion is useful, and which checks help keep a result meaningful in context.
One Rydberg equals 13.6056931223 Electronvolt. The tool calculates your result by multiplying the number you enter by 13.6056931223, using the documented energy factors for the selected source and target units.
Confirm that your source value is expressed in Rydberg (Ry) before you begin, then verify that the result is needed in Electronvolt (eV). Keep more decimal places when the receiving form, specification, or measurement process requires them.
Use this converter when a worksheet, specification, device, or collaborator provides a value in Rydberg but your next step expects Electronvolt. The calculation stays in your browser, so you can test alternate values without uploading the measurement.
