What is a Russian archin?

It is an old Russian unit of length equal to 28 English inches or approximately 0.7112 meters, commonly used before metrication.

What does Earth's equatorial radius represent?

It is the distance from the Earth's center to the equator measured along the equatorial plane used in geodesy and related fields.

Why convert Russian archin to Earth's equatorial radius?

To relate historical Russian length measurements to modern geodetic references important for mapping, aerospace, surveying, and restoration.
