What is a US Survey Chain?
The US survey chain (∼20.1168 m) used the US survey foot. This measurement was key in the rectangular survey system that mapped the American frontier.
What is Earth's Equatorial Radius?
Earth's Equatorial Radius is the radius of the Earth measured at the Equator. Its value is approximately 6,378.1 kilometers (3,963.2 miles). Due to Earth's rotation, it is slightly larger than the polar radius.
