Units explained
Square US Survey Mile
A square US survey mile is approximately 2,589,998 m², slightly larger than the international square mile.
Derived by squaring the US survey mile (5280 US survey feet).
Square US survey miles appear in older US Public Land Survey System records and state plane coordinate systems pre-dating 2023.
Defined in 1893; retired January 2023.
Square Meter
A square meter is the SI base unit of area, defined as the area of a square with sides of one meter. It is the universal scientific unit for area.
Defined by squaring the meter, which was redefined in 2019 in terms of the speed of light. The meter itself was originally proposed by the French Academy of Sciences in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Square meters are the universal SI unit for area, used in real estate (most countries outside the US/UK), construction, physics, engineering, materials science, biology, and nearly all scientific contexts worldwide.
Meter adopted as SI base unit in 1960; current exact definition via speed of light dates to 2019.
