Chain - engineer's or Ramsden's popular
A usually metal chain used to measure length and distance. Less commonly used in land surveys than a Gunter's or surveyor's chain, the engineer's or Ramsden's chain is 100 feet in length, with 100 1-foot links. The terms "engineer's chain" and "Ramsden's chain" apply primarily to the measuring utensil itself and not to any particular unit of length.
