Units explained
Square Mile
A square mile is an imperial unit of area equal to exactly 2,589,988.110336 m². It is used for measuring large land areas in the United States and the United Kingdom.
Derived by squaring the statute mile (5,280 feet). The mile was standardized via the 1959 International Yard and Pound Agreement.
Square miles are used for US and UK regional geography (county areas, lake sizes, large parks), national statistics, and military range descriptions. 1 mi² = 640 acres = 2.589988 km².
Mile dates to Roman antiquity; modern exact value standardized in 1959.
Square Pole
A square pole is identical to a square rod, equal to approximately 25.293 m². 'Pole' is a regional name used in some US and British contexts.
Identical to square rod and square perch; differs only in regional naming preference.
Square poles appear in some historical US land records, particularly in mid-Atlantic states with strong English colonial heritage.
Standardized via the 1959 International Yard and Pound Agreement.
