How to Convert Link to Earth's Polar Radius
1 li = 3.16463487180396e-08 R_p
Example: convert 15 li to R_p:
15 li = 15 × 3.16463487180396e-08 R_p = 4.74695230770593e-07 R_p

Link
A link, specifically Gunter's link, is a unit of length equal to 7.92 inches, or 1/100 of a chain.
History/Origin
The link is part of Gunter's chain, a surveying tool invented by Edmund Gunter in the 17th century.
Current Use
The link is an obsolete unit of measurement, but may be found in old land surveys.
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.
