A link, also called a Gunter’s link, is a unit of length in the imperial and US systems. Links were commonly used in measuring land in the English-speaking world before the 20th century, but are now rarely used. Link is usually abbreviated as l., li. or lnk. It was invented by Edward Gunter (1581-1626), a professor of astronomy at Gresham College, London, the same man who made the chain. He made the link as a low technology piece of equipment that could survey small areas of land very accurately, whereas the chain could measure towns and large areas of land.

1 link = 1100 chain
= 7+2325/ 7.92 inches
= 201.168 millimetres=20.12 centimetres

It is used rarely nowadays, but is sometimes used in agriculture, like the chain. It is exactly like the small metal loops in a chain, and is therefore called a link.
