What is the area of one section of land?

The area of one section of land is defined as 640 acres. This measurement is based on the Public Land Survey System (PLSS) used in the United States, where one section is equal to one square mile. Since there are 640 acres in a square mile (1 mile = 5280 feet and 1 square mile = 5280 feet x 5280 feet = 27,878,400 square feet; thus, 640 acres = 43,560 square feet/acre x 640 acres = 27,878,400 square feet). This fundamental unit is essential for understanding land measurement in planning, zoning, and development contexts. Knowing that a section consists of 640 acres can aid professionals in calculating land use, agricultural production areas, and property boundaries accurately.
