chain (Geography Dictionary)

chain : A unit of length equal to 66 feet (20.117 m), used especially in public land surveys in the United States; 10 square chains is equal to 1 acre (0.40 hectares). Though the literal chains used to measure this distance have long been superseded, surveying tapes are often still called “chains”, and measuring with a tape may be called “chaining”.
