What does the classical electron radius represent?

It is a characteristic scattering length defined classically and related to the electrostatic self-energy matching the electron rest energy, not a physical size.

Why convert Electron radius (classical) to kiloparsec?

To enable comparisons between microscopic electromagnetic scales and astronomical distances, useful in physics and astronomy contexts.

Is the conversion commonly used for direct measurements?

No, because of the vast scale difference, it is typically used for theoretical or normalization purposes rather than direct measurement.
