How large is a section in the rectangular government survey system?

In the rectangular government survey system, a section is defined as a square piece of land that occupies one mile on each side, totaling 640 acres. This system is designed to create a clear framework for mapping and describing land in the United States, particularly in the west, allowing for straightforward division and conveyance of property. Each township, which is 36 square miles, is divided into 36 sections, with each section representing one square mile. This consistency in measurement makes it easier to identify and manage land parcels in real estate transactions.
