An erg is a unit of energy in the CGS system, measuring mechanical, thermal, or electromagnetic energy, equal to 1×10⁻⁷ joule.

What does the Rydberg constant represent?

The Rydberg constant is a fundamental physical constant associated with atomic spectral lines and ionization energies in hydrogen-like atoms.

When should I use this conversion?

Use this conversion to relate classical energy measurements to quantum atomic scale units in fields like spectroscopy, astrophysics, and quantum chemistry.
