What does Earth's polar radius represent?

It is the distance from Earth’s center to the mean geographic pole along the rotation axis, defined as the semi-minor axis of a reference ellipsoid like WGS84.

What is caliber [cl] in this context?

Caliber here refers to a length-related term in firearms and artillery, denoting barrel internal diameter or multiples of that bore diameter.

Why convert Earth’s polar radius to caliber units?

To conceptually compare very large geodetic lengths with firearm dimensions, useful in engineering or ballistics studies examining different scales.
