What is a rod as a unit of length?

A rod is a traditional English unit of length equal to 16.5 feet or exactly 5.0292 metres, historically used in surveying and land measurement.

What does the classical electron radius represent?

It is a derived length scale representing a characteristic scattering length in physics, defined by classical constants, not the literal physical size of an electron.

Why convert from rod to electron radius?

To translate macroscopic length measurements into atomic-scale units useful for physics research, electromagnetic scattering analysis, and educational purposes.
