Length of engineer’s chain is

  • A.100 ft long
  • B.66 ft long
  • C.33 ft long
  • D.None of these

Answer: A

An engineer's chain is 100 ft long.

The engineer's chain has 100 links, each 1 foot long, giving 100 feet. It was used for engineering surveys in feet.

The 66 ft chain is Gunter's chain (surveyor's chain) of 100 links of 0.66 ft, used for land measurement because 10 square Gunter's chains make an acre. 33 ft is the half-length revenue chain used in India. Metric surveys now use 20 m and 30 m chains.
