About Square Chains
A square chain (ch²) is a surveying unit equal to the area of a square with sides of one Gunter's chain (66 feet or ~20.12 m), approximately 404.69 m². Ten square chains equal exactly one acre, making it the natural subdivision unit in traditional land surveying. The US Public Land Survey System used chains to lay out townships and sections, and square chains appear throughout old legal property descriptions and government land grants across North America. One square chain equals exactly 16 square rods.
About Square Feet
A square foot (ft²) is an imperial unit of area equal to a square with sides of one foot (12 in × 12 in or 144 in²). It is the standard for measuring floor space in the United States and some other countries. A typical bedroom is 100-150 ft², and the average American house is roughly 2,000-2,500 ft². This unit dominates real estate listings, flooring sales, and construction in countries using imperial measurements.
