What is a span (cloth)?

A span (cloth) is a traditional length unit based on the distance between the tip of the thumb and little finger of an outstretched hand, historically used to describe narrow fabric widths.

What does the Bohr radius represent?

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

Why convert from span (cloth) to Bohr radius?

The conversion allows expressing familiar macroscopic textile measurements in atomic-scale units commonly used in quantum chemistry and physics for analysis and education.
