It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581-1626) long before the development of the theodolite and other more sophisticated equipment, enabling plots of land to be accurately surveyed and plotted, for legal and commercial purposes. The chain of 100 limks measures exactly 1/80 of a mile or 5280/80 = 66 feet. One link = 7.92 inches or 0.66 feet (Image). |
