What is the Rydberg constant used for?

It is used to calculate wavelengths and transition energies in hydrogen-like atoms, determine ionization energies, and calibrate spectrometers.

What does kilocalorie (IT) represent?

Kilocalorie (IT) is a unit of energy equal to 1,000 international-table calories, commonly used in thermodynamics and engineering heat calculations.

Why is the conversion factor so small?

Because the Rydberg constant expresses atomic-scale energy which corresponds to extremely small amounts when converted to macroscopic thermal energy units like kilocalorie (IT).
