A common forestry and land survey term that is equivalent to 66 linear feet. Often referred to as simply "chain", this term is more formally known as the surveyor's or Gunter's chain. A chain is broken into 100 equal parts, or links. One (1) mile is equal to 80 chains. A one (1) mile square piece of land (one section or 640 acres) is 80 chains on each side. Although an engineer's or Ramsden's chain is also used to measure length in surveys, the generic term "chain" when used in reference to land measurements refers to the unit of length (66 feet) represented by the Gunter's or surveyor's chain.
