What is a perch and where was it used?

A perch, also known as a rod or pole, is an historical unit of length equal to 16.5 feet or 5.0292 meters, mainly used in surveying and land measurement in earlier times.

What does the classical electron radius represent?

It is a derived length scale in physics representing the distance where the classical electrostatic self-energy of a charge equals the electron's rest energy, used in scattering and electromagnetic calculations.

Why would I convert from perch to classical electron radius?

This conversion helps translate large historical land measurements into a very fine atomic-scale unit, useful for relating macroscopic distances to fundamental physical constants in physics and astrophysics.
