How to Convert Rydberg to Megaelectron Volt

To convert from Rydberg (Ry) to Megaelectron Volt (MeV), multiply the value by 1.360569e-5.

Formula: MeV = Ry × 0.0000136057

Reverse: Ry = MeV × 73,498.6565266218

Step-by-Step Example

Start with your value in Rydberg. For example: 5 Ry
Multiply by the conversion factor: 5 x 1.360569e-5
The result is: 6.802845e-5 MeV

About Rydberg

The rydberg (Ry) is a unit of energy and work. One rydberg equals 2.179872 × 10^-18 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.

About Megaelectron Volt

The megaelectron volt (MeV) is a unit of energy and work. One megaelectron volt equals 1.602177 × 10^-13 joules. UnitConvertLab converts it against every other energy unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: energy calculations, engineering and science, education.
