In the rectangular government survey system, how large is a section?

In the rectangular government survey system, a section is defined as an area of 640 acres. This system, also known as the Public Land Survey System (PLSS), divides land into townships, and each township is further divided into sections. Each section is one square mile in size, which is equivalent to 640 acres.

Understanding this measurement is important for land appraisal and transactions, as it provides a standardized way to quantify large tracts of land. The concept of sections being 640 acres also aids in determining property boundaries and assessing land value based on size.
