How many acres are there in one section within the Public Land Survey System?

In the Public Land Survey System (PLSS), one section is defined as an area that encompasses 640 acres. This is based on the standardized measurement used in the PLSS, where a complete township is typically divided into 36 sections, each of which measures one square mile. Since one square mile contains 640 acres, it follows that one section also contains this same number of acres. This understanding is fundamental to the interpretation and navigation of land within the PLSS, which is crucial for real property appraisal and management.
