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.
Acre (ac)
An acre is a traditional Anglo-American land unit equal to 43,560 square feet, or roughly 4,047 m². It originated from medieval English farming, where an acre represented the amount of land a yoke of oxen could plow in one day—reflecting its deep agricultural roots. The acre remains widely used in the United States and the UK (in certain contexts), especially in real estate, agriculture, and land conservation. It is culturally intuitive for rural populations, where land plots have been measured in acres for centuries. The unit's longevity demonstrates how historical agricultural practices shaped modern land evaluation systems. Despite its lack of coherence with the metric system, the acre endures because of its cultural familiarity and long-standing legal integration.
