About these units
Square Mile (mi²)
A square mile equals 640 acres or about 2.58999 km². It is the primary unit for describing large areas in the United States and the UK, particularly in geography and land-use planning. City sizes, county boundaries, national park dimensions, and lake surfaces are often expressed in square miles. Because of its large scale, it is ideal for measuring political subdivisions, conservation zones, and territorial claims. The square mile also appears in demographic statistics—such as population density—and in historical surveys of American frontiers, where square-mile sections formed the backbone of land distribution policies.
Cuerda (cuerda)
The cuerda is a traditional land unit used primarily in Puerto Rico, where it is legally defined as 3,930.395625 square meters—slightly smaller than a hectare and slightly larger than an acre. Cuerdas are widely used in real estate transactions, agriculture, and land management throughout the island. Farmland, forest preserves, and rural homesteads are typically measured in cuerdas rather than square meters or acreage. The cuerda's historical roots likely tie back to Spanish colonial surveying practices, but unlike many colonial units, the cuerda has been standardized, stabilized, and legally maintained well into the modern era. Its continued use reflects cultural identity as much as practicality; Puerto Ricans often conceptualize land parcels in cuerdas, making it a central part of the island's land-economy vocabulary.
