What is Earth's polar radius?

Earth's polar radius is the distance from the Earth's center to the mean geographic pole along the rotation axis, representing the semi-minor axis of a geodetic reference ellipsoid such as WGS84.

What does the classical electron radius represent?

The classical electron radius is a derived length scale connecting the classical electrostatic self-energy of a charge to the electron's rest energy and serves as a characteristic scattering length in physics.

Why convert from Earth's polar radius to classical electron radius?

This conversion enables researchers to relate very large geodetic length scales to atomic scale lengths, facilitating interdisciplinary studies across Earth sciences and atomic and particle physics.
