What is the foot (US survey) used for?

It is historically used in U.S. land surveying, mapping, cadastral measurements, and certain engineering projects that require compatibility with older records.

What does the Bohr radius represent?

The Bohr radius is the atomic unit of length corresponding to the most probable distance between a hydrogen atom’s nucleus and its electron in the ground state.

Why are conversions from foot (US survey) to Bohr radius so large numerically?

Because the Bohr radius is an extremely small unit, converting from a macroscopic length like the foot results in very large numbers.
