What is a Square Mile and a Square Meter?
The square mile (symbol: mi², sq mi) is an imperial and US customary unit of area. It represents the area of a square with sides that are each one statute mile long.
The square meter (symbol: m²) is the SI derived unit of area. It represents the area of a square with sides that are each one meter long.
Note: The Square Mile is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Square Meter belongs to the metric (SI) system.
History of the Square Mile and Square Meter
Derived from the mile, a unit of distance with Roman origins, the square mile became a standard unit for measuring large land areas in the imperial system, particularly within the British Empire and the United States. It's often used for geographic and administrative divisions.
Derived directly from the meter, which was defined during the French Revolution, the square meter became the standard unit of area within the International System of Units (SI) established in 1960. Its adoption provided a consistent, universally accepted measure for scientific, technical, and everyday area calculations.
