A link, also called a Gunter’s link, was a unit of length in the imperial and US customary systems. Links were commonly used in measuring land in the English-speaking world before the twentieth century, but are never used. Link is abbreviated as ln. It was invented by Edmund Gunter, 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
