What does the classical electron radius represent?

It is a theoretical length scale derived from fundamental constants related to electron electrostatic energy and rest energy, used in scattering physics.

Why convert electron radius to millimeters?

Converting to millimeters provides a more intuitive scale for engineering and scientific applications where familiar length units are preferred.

Can this conversion be used for physical electron measurements?

No, since the electron radius is a characteristic scale and not the literal size of an electron, it is not used for physical size measurements.
