What is the Rydberg constant used for?

It is used to calculate wavelengths and transition energies in hydrogen-like atoms, interpret spectral lines, and determine ionization energies in atomic and quantum physics.

Why convert from Rydberg constant to calorie (IT)?

This conversion helps relate atomic-scale energy values from spectroscopy and quantum mechanics to classical thermodynamic units used in older engineering and steam table data.

Is the calorie (IT) unit still used today?

The calorie (IT) is mostly historical and has been replaced by the joule in modern measurements, but it remains relevant for analyzing legacy data and classical thermodynamics.
