About these units
Square Chain (ch²)
A square chain equals the area of a square one chain (~66 feet) per side, resulting in 4,356 square feet, or exactly 1/10 of an acre. This unit is closely linked to the chain, a surveyor's unit standardized by Edmund Gunter in the 17th century. Because 10 square chains make an acre, survey calculations for early colonial and American lands were extremely efficient. Square chains allowed surveyors to map and divide land rapidly using ropes or metal chains, producing a legacy seen in long, straight property lines still visible today across rural landscapes.
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.
