What does one Bohr radius represent?

One Bohr radius represents the most probable distance between the nucleus and the electron in the hydrogen atom's ground state, serving as an atomic unit of length.

Why convert Bohr radius to light years?

Converting Bohr radius to light years helps express atomic-scale distances in terms of cosmic scales, which is useful in bridging quantum mechanical and astrophysical perspectives.

Are the values from this conversion practical for astronomy?

No, since the Bohr radius is extremely small, the corresponding light year values are very tiny and often not practical for direct astronomical applications.
