Convert chain [ch] to Earth's polar radius
Please provide values below to Convert chain [ch] to Earth's polar radius, or vice versa.
What is a Chain?
The chain (22 yards or 20.1168 m) was crucial in land surveying. Invented by Edmund Gunter in 1620, 10 square chains equal 1 acre. Modern surveyors still use 'chain' terminology.
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.
