What is a link (li) in length measurement?

A link is a historic English unit used in surveying, equal to 0.66 feet or 0.201168 meters, mainly from 18th–19th century land measurement practices.

What does Earth's distance from the Sun represent in this conversion?

It represents the astronomical unit (AU), the average distance between Earth and the Sun, defined as exactly 149,597,870,700 meters.

Why would someone convert links to Earth's distance from the Sun?

To translate historical land measurements into a universal astronomical scale, helping compare local distances with cosmic distances for educational and analytical purposes.
