What is Earth's polar radius?

Earth's polar radius is the distance from Earth's center to the geographic pole along its rotation axis and defines the semi-minor axis of geodetic reference ellipsoids like WGS84.

What is a Russian archin?

The Russian archin, or arshin, is a historic Russian length unit approximately equal to 0.7112 meters, used before metrication in trade and tailoring.

Why convert Earth's polar radius to Russian archin?

Conversions help translate modern geodetic data into historical units for understanding old Russian maps, documents, and restoration projects.
