What is a chain (US survey)?

It is a traditional unit of length equal to 66 US survey feet, historically used in U.S. land surveying, approximately 20.1168 metres.

What does the Bohr radius represent?

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

Why convert from chain (US survey) to Bohr radius?

This conversion helps relate large-scale land surveying measurements to atomic-scale distances used in physics and chemistry, useful for interdisciplinary studies.
