Understanding the Square Mile (mi²)

A square mile (mi²) equals 640 acres or approximately 2.59 square kilometers. It's used to measure large land areas, such as counties or national parks, primarily in the United States and the UK.

For example, Yellowstone National Park spans about 3,472 square miles. This unit is essential for large-scale geographical and administrative planning.

The square perch is an antiquated unit of area measurement, synonymous with the square rod and square pole. It denotes the area of a square with sides of one perch (16.5 feet), amounting to 272.25 square feet or about 25.293 square meters.

Historically, the square perch was utilized in land measurement, particularly in the United Kingdom and its colonies. Although it's largely obsolete today, the unit persists in historical land records and legal documents. Professionals dealing with historical land assessments or restoration projects may encounter this unit and should be adept at converting it to modern measurements.

Recognizing the square perch is essential for accurate interpretation of historical property data and ensuring consistency in land-related documentation.
