A square pole, also known as a square perch, is an obsolete unit of land area measurement that was historically used in some English-speaking countries, including the United States and the United Kingdom. It is part of the older system of land measurement.
One square pole is equivalent to one square perch. In terms of modern measurements, one square pole is approximately equal to 25.29285264 square meters (m²) or 0.00625 acres.
As with other outdated units of land area measurement, the square pole is no longer commonly used in modern land transactions or legal documents. More standardized systems of measurement, such as square meters and square feet, have largely replaced these units.
In the context of land surveying and property descriptions in the United States, a "section" refers to a specific unit of land division. It is part of the Public Land Survey System (PLSS), which was established to survey and divide land in the United States, particularly in the western and central parts of the country.
