What does the Rydberg constant measure?

It is a fundamental physical constant that defines the scale for atomic spectral lines, representing the limiting wavenumber for hydrogen-like atomic transitions and related to the ionization energy of hydrogen.

How is a watt-second related to other energy units?

A watt-second is equal in dimension and value to one joule and represents the energy transferred by one watt of power sustained for one second.

Why are the conversion values so small?

Because the Rydberg energy corresponds to atomic-scale energy levels, it is extremely small compared to everyday energy units, resulting in very small conversion outputs.
