What is a Square Meter and a Square Mile?

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.

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.

Note: The Square Meter is part of the metric (SI) system, primarily used globally in science and trade. The Square Mile belongs to the imperial/US customary system.

History of the Square Meter and Square Mile

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.

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.
