About these units
Square Yard (yd²)
A square yard equals 9 square feet or 0.836 m². Historically used in the British Empire and still used in the US and UK for certain materials, the square yard appears frequently in carpeting, turf, paving stones, and textiles. Its intermediate size makes it suitable for areas larger than a square foot but smaller than a square meter, giving it usefulness in construction and home improvement. Although square meters have replaced square yards in most official contexts, industries such as carpeting, sports field design, and gardening continue to use this practical measure.
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.
