About These Units
Chain (ch)
A chain (ch) is a surveying unit equal to 66 feet, 22 yards, or 20.1168 meters. Invented by Edmund Gunter in 1620, chains are still used in land surveying and property descriptions. Ten chains equal one furlong, 80 chains equal one mile.
Astronomical Unit (AU)
An astronomical unit (AU) is the average distance from Earth to the Sun: approximately 149.6 million kilometers or 93 million miles. AUs measure distances within our solar system. Mars is 1.52 AU from the Sun, Jupiter is 5.2 AU.
