What is the area covered by one section of land?

One section of land in the Public Land Survey System (PLSS) is defined as one square mile, which equates to 640 acres. This measurement is fundamental for land description and division in the United States, particularly in rural areas. Each section is further subdivided into smaller fractions such as halves or quarters for more detailed land surveys or transactions, but the entire section itself always maintains the area of 640 acres. This standardized measurement is critical for land management, real estate, and surveying practices, ensuring clarity and consistency across land transactions and legal documentation.
