th of a square mile
The shape of an acre can vary, but it is often represented as a rectangle measuring 66 feet by 600
feet, a configuration that originated from historical farming practices.
The acre is predominantly used in the United States, Canada, and some Commonwealth countries for:
- Land surveying: It is the standard unit for real estate transactions and land records.
- Agricultural land: Farmers and landowners often use acres to describe the size of fields and plots.
- Public spaces: Parks, forests, and other large areas are frequently measured in acres.
In contrast, most other countries use the metric system, where land area is measured in hectares (1 hectare = 2.471 acres
).

Historical of Square Mile
Hearths of the square mile are in the ancient systems of the Roman and British ones, though the probable existence of the idea existed before the Romans and was used in the United States due to the Public Land Survey System (-) in the late 18th century. The PLSS aimed to organize land into townships and sections with a view to selling the land. They were subdivided into thirty-six townships, each of which was thirty-six square miles, and were further subdivided into thirty-six sections of one square mile, or six hundred and forty acres of land.
Public surveying as practiced by this system was used in the westward expansion of the United States and was instrumental in the formation of the country.
Use in Land Measurement Today
The square mile remains a standard unit for measuring large areas of land. Its primary uses include:
- Land Division: In the PLSS, therefore, square miles are used as units to subdivide land into easily measurable parts and aliquots.
- Agriculture: It is used to measure large-scale farms, ranches, farming areas, or regions for large-scale farming activities. Because acres are even smaller than hectares, acres are preferred for describing the actual plots or fields of farmland within a square mile.
- Real Estate: Square miles assist in estimating the area of extensive tracts of land or development ventures mainly in the country or city outskirts.
Notable Uses of the Acre in Agriculture and Real Estate
Since 1
square mile equals 640
acres, the acre serves as a more detailed unit for specific land uses within the square mile:
- Agriculture: Acres are used by farmers in order to measure the planting areas, the yield of crops, and the amount of water to be used in farming, while square miles give the broad perspective of the regional planning.
- Real Estate: This is because square miles are helpful in outlining layouts in large-scale developments like new neighborhoods or industrial tracts.
