About these units
Township (township)
A township, as used in the U.S. Public Land Survey System (PLSS), is an area equal to 36 square miles, arranged as a 6-mile × 6-mile square. It is a cornerstone unit of American land division, originating during the late 18th-century settlement of the American frontier. Townships standardized how land was surveyed and sold, allowing the federal government to systematically divide territory for settlement, homesteading, and revenue generation. They were subdivided into 36 sections, each one square mile in area. This grid-based system profoundly shaped American geography. Roads, property lines, agricultural fields, and county boundaries in much of the Midwest and West follow township geometry. Even today, PLSS townships remain legally relevant in land deeds, zoning regulations, and cadastral surveys.
Square Foot (US Survey) (ft² (US))
The US survey square foot is defined using the US survey foot and differs minutely from the international square foot. While the difference is negligible in everyday contexts, in land surveying even tiny discrepancies matter because property boundaries, right-of-way extents, and engineering alignments may accumulate errors over long distances. Surveyors and civil engineers must interpret historical documents using survey-based values to ensure legal consistency with old plats, deeds, and boundary descriptions.
