What is Earth's Polar Radius?
Earth's Polar Radius is the radius of the Earth measured from its center to the North or South Pole. Its value is approximately 6,356.8 kilometers (3,950.7 miles), slightly smaller than the equatorial radius due to Earth's oblate shape.
What is a US Survey Link?
The US survey link (∼20.1168 cm) was based on the US survey chain. These small units allowed precise land measurements in the rectangular survey system, with township maps showing dimensions in links and chains until metric conversion.
