What is a Link (li) unit?

Link (li) is a historic English unit of length used mainly in 18th and 19th century surveying, equal to 0.66 feet or about 0.201168 meters.

Why convert from Link to Earth's equatorial radius?

Converting from Link to Earth's equatorial radius helps relate old land measurements to modern geodetic reference systems for accurate mapping and analysis.

Is the conversion exact for all locations on Earth?

No, the Earth's equatorial radius used is a fixed geodetic value and does not account for local radius variations due to the Earth's shape and surface undulations.
