What is a hand unit used to measure?

The hand is a traditional length unit primarily used to measure the height of horses at the withers.

Why convert from hand to Bohr radius?

Converting hand to Bohr radius helps relate large-scale human measurements to atomic-scale distances in scientific and educational contexts.

Is the Bohr radius useful outside atomic-scale physics?

No, the Bohr radius is primarily used in atomic physics, quantum chemistry, and related scientific fields and is not suited for biological or equestrian measurements.
