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 Meters
A square meter (m²) is the SI derived unit of area, equal to the area of a square with sides of one meter. It is the standard worldwide for measuring room sizes, apartments, houses, and land plots. A king-size bed occupies about 4 m², a parking space is roughly 12-15 m², and a small apartment might be 50-60 m². This unit is fundamental in real estate, construction, architecture, and interior design globally.
