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.
Are (a)
An are is a metric land unit equal to 100 m², originally invented during the development of the metric system but now largely overshadowed by the hectare (100 ares). Although rarely used independently in modern measurement, the are survives in real estate transactions in parts of Europe, where small land parcels—such as garden plots or rural homesteads—may be expressed in ares. It remains important historically, as it served as a transitional unit bridging the earliest metric innovations with modern large-scale land measurement practices.
