Gunter's chain
Gunter's chain (also known as Gunter's measurement) is a distance-measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. Gunter developed a precise measuring chain of 100 links and a total length of 66 feet. These, the chain and the link, became statutory measures in England and subsequently the British Empire.
