What is a fingerbreadth?

A fingerbreadth is an informal, non-standard length unit roughly equal to the width of an adult finger, often used for quick estimates.

What does a.u. of length [a.u., b] represent?

It represents the atomic unit of length, defined by the Bohr radius, used in atomic physics to express distances on an atomic scale.

Why convert from fingerbreadth to atomic units of length?

To translate everyday rough measurements into precise atomic-scale units, aiding in bridging human-scale intuitions with atomic and quantum physics measurements.
