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 (U.S. Survey)
Today, a square mile is subdivided from the Roman-British systems, and although the meaning of a U.S. survey definition is much more precise, it is rooted in the General Land Office surveying methods in the eighteenth and nineteenth centuries. The unit was made constant for use in the westward expansion of the United States in the division of land and the layout of property boundaries.
Square miles were important for using the most popular land dividing method called the Public Land Survey System, which divided it into townships, sections, and parcels in order to sell and manage it more efficiently. The areas of each township were intended to be 36
square miles and subdivided into thirty-six 1
square mile tracts.
Use in Land Measurement Today
The square mile (U.S. survey) remains a key unit in the measurement of large land areas in the United States. It is used in the following contexts:
- Geographic Areas: Square miles are commonly employed in discussing the area of cities, counties, states, and some other territories.
- Land Division: The sections and townships used in the PLSS are described with reference to square miles in surveying and allocation of land.
- Real Estate and Agriculture: Square miles are used as a unit of measurement when it comes to large chunks of agricultural or unimproved land, mostly in rural or government land.
Notable Uses of the Acre in Agriculture and Real Estate
Since 1 square mile equals 640
acres, the acre becomes a smaller, more practical unit for individual parcels within a square mile.
- Agriculture: Consumers and producers estimate planting areas and output in terms of acres, while square miles include a broader planning unit at the regional level.
- Real Estate: It assists in estimating and planning other small or big-scale developments on large pieces of land, such as subdivisions of land or business use.
