What is the classical electron radius?

It is a derived length scale representing a characteristic scattering length in particle physics, not a literal size of the electron.

Why convert electron radius to megameters?

To express very small atomic scale lengths using units suitable for large terrestrial distances, enabling interdisciplinary comparison.

Is this conversion practical for engineering purposes?

No, due to the extremely small value of the electron radius relative to megameters, this conversion is mainly theoretical.
