Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
Russian Archin
The Russian archin is an obsolete Russian unit of length, equal to about 28 inches or 71.12 centimeters.
History/Origin
The archin was a common unit of measurement in Russia before the adoption of the metric system.
Current Use
The archin is no longer in use.
