What is Earth's polar radius?

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

How long is one Roman mile?

A Roman mile equals 1,000 double steps or about 5,000 Roman feet, approximately 1,480 meters.

Why convert Earth's polar radius to the Roman mile?

Converting helps relate modern geodetic measurements to ancient units for uses in historical cartography, archaeology, and classical research.
