What is Earth's polar radius?

Earth's polar radius is the distance from the Earth's center to the mean geographic pole, representing the semi-minor axis in reference ellipsoids like WGS84.

What is the Bohr radius used for?

The Bohr radius is an atomic unit of length used in quantum chemistry and atomic physics to express typical distances like the most probable electron-nucleus separation in hydrogen.

Why convert Earth's polar radius to Bohr radius?

Converting these units helps bridge large-scale Earth measurements with atomic-scale distances useful in scientific research involving both geodesy and atomic-scale simulations.
