Are a.u. of length and Bohr radius the same unit?

Yes, both units represent the atomic length scale corresponding to the Bohr radius and are equivalent in value.

Why convert between these seemingly identical units?

Conversion helps users align representations according to specific conventions in atomic physics or quantum chemistry, supporting clarity in computational results.

Can I use this conversion for macroscopic length measurements?

No, these units are intended for atomic-scale lengths within nonrelativistic quantum frameworks and are not suitable for macroscopic scales.
