How many acres are in one section of land?

One section of land is defined as an area that contains 640 acres. This measurement is a standard of land division used in the United States, particularly in the context of the Public Land Survey System (PLSS). Each section is one square mile, and since there are 640 acres in a square mile, this figure is consistently applied across various uses in real estate, land appraisal, and property assessment. Understanding this basic unit is crucial for appraisers and anyone involved in land transactions, as it allows for accurate calculations and assessments of larger parcels by knowing how many sections are involved. The significance of this measurement in land management and real estate practices contributes to its widespread recognition and use.
