What does the classical electron radius represent?

It is a theoretical length scale that characterizes the distance where the electrostatic self-energy of a charge equals the electron rest energy, used in physics calculations.

Why are the conversion results so large?

Because millimeters are macroscopic units, while the classical electron radius is extremely small at an atomic scale, leading to large numeric values when converted.
