What does the Rydberg constant represent?

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

What is a Calorie (nutritional)?

In nutrition, it refers to the kilocalorie (kcal), which equals 1,000 small calories and quantifies energy available from food.

Can I use this conversion for everyday diet planning?

Since the energy scales differ greatly, this conversion is mainly useful in scientific research rather than typical dietary calculations.
