Description

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.

Square Chain (ch²)

The square chain is a historical unit of area measurement, primarily used in land surveying. One square chain is defined as the area of a square with sides measuring one chain (66 feet) each, equating to 4,356 square feet or approximately 404.686 square meters.

This unit was commonly employed in the United States and other countries that used the imperial system, especially for agricultural and land division purposes. Although modern surveying has largely transitioned to metric units, understanding the square chain is essential for interpreting historical land records and legal documents.

In contemporary contexts, the square chain is occasionally referenced in rural property descriptions and by professionals dealing with land assessment and historical property boundaries.
