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.

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.

1. A term, frequently used in connection with zoning requirements, which means the maximum number of building units per acre or the number of occupants or families per unit of land area (acre, square mile, etc.). 2. The ratio of developed or improved area to total land area.

For area measurements, square units refers to total area, while units square refers to the number of units on each side (the length of each side of a square). For example, consider two square pieces of land: one is 7 square miles, and the other is 7 miles square. The total area of the first parcel is 7 square miles. Since the parcel is a square, the length of each side is equal to the square root of 7 square miles, which is approximately 2.65 miles. In contrast, the length of each side of the second parcel is 7 miles, according to the definition above. The total area is therefore 7 miles x 7 miles = 49 square miles.
