Why convert millimeters to Bohr radius units?

This conversion is used to translate engineering-scale length measurements into atomic units important in quantum chemistry and atomic physics.

What is a Bohr radius?

The Bohr radius is the atomic unit of length representing the most probable electron-nucleus distance in a hydrogen atom's ground state.

Are there limitations to this conversion?

Yes, the Bohr radius is extremely small so converting larger millimeter values results in very large numbers which may be difficult to handle.
