What does the Rydberg constant represent in energy terms?

It corresponds to the ionization energy of a hydrogen atom under an idealized infinite nuclear mass approximation and sets a scale for atomic spectral lines.

Why convert Rydberg constant values to ergs?

Converting to ergs helps express atomic-scale energies in the CGS system, useful for compatibility with classical mechanics, electromagnetism, and astrophysical energy reporting.

What is an erg and where is it commonly used?

An erg is a CGS unit of energy equal to 1×10⁻⁷ joule, mainly used in astrophysics, classical lab calculations, and interpreting historical scientific literature.
