What is a barleycorn?

A barleycorn is a historic length unit equal to one third of an inch, originally based on the length of a grain of barley.

What is a Bohr radius?

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

Why convert barleycorn to Bohr radius?

This conversion links traditional British measurements often found in historical contexts to atomic-scale units used in quantum chemistry and physics.
