What is the Bohr radius used for?

The Bohr radius is used in quantum chemistry and atomic physics to represent the typical distance between the nucleus and electron in a hydrogen atom.

Why convert Bohr radius to Planck length?

Converting Bohr radius to Planck length helps relate atomic-scale distances to the fundamental length scale in quantum gravity and theoretical high-energy physics.

Can this conversion be used for experimental measurements?

No, this conversion is mainly theoretical since the Planck length is many orders of magnitude smaller than atomic distances, making direct experiments impossible.
