What is the classical electron radius?

It is a derived length scale representing the distance related to the electron's electrostatic self-energy equal to its rest energy, used in scattering and theoretical physics.

Why convert Electron radius (classical) to Megaparsec?

To relate microscopic electromagnetic scattering parameters with cosmological distance scales, aiding analyses that span atomic to galactic scales.

Is the Electron radius a physical size of the electron?

No, it is a characteristic scattering length, not a physical measure of the electron's size.
