What is a therm (US)?

A therm (US) is a unit of heat energy equal to 100,000 British thermal units, commonly used to measure natural gas and heating energy in the United States.

What does the Rydberg constant represent?

The Rydberg constant is a fundamental physical constant related to atomic spectral lines and the ionization energy of hydrogen-like atoms.

Why convert therm (US) to the Rydberg constant?

This conversion helps connect practical large-scale energy measurements with atomic-scale energy references used in spectroscopy and quantum mechanics.
