What is a kilocalorie (IT)?

A kilocalorie (IT) is a unit of energy equal to 1,000 international-table calories, where one international-table calorie is defined as 4.1868 joules.

What does the Rydberg constant represent?

The Rydberg constant is a fundamental physical constant that characterizes atomic spectral lines, particularly for hydrogen-like atoms, related to the ionization energy in atomic physics.

Why convert from kilocalorie (IT) to Rydberg constant?
