A square mile (mi²) is an imperial unit of area equal to the area of a square with sides of 1 mile. It equals 640 acres or approximately 2.59 square kilometers.

History

The square mile has been used since the establishment of the statute mile in England. As settlements expanded, the square mile became the standard for measuring large tracts of land, counties, and states.

Current use

Square miles are used primarily in the United States and the United Kingdom to express the area of cities, counties, states, and natural parks. Population density is often stated in people per square mile.

History

The square decimeter is part of the original metric measurement system. While less commonly used than cm² or m², it serves as a practical intermediate unit in certain technical and educational settings.
