About Acre and Square Yard
What is the Acre?
The acre equals exactly 4,046.8564224 square meters (or 43,560 square feet) and is the standard unit for American and British farmland, real estate, and recreational property. The unit's origin is medieval: an acre was the area a yoke of oxen could plow in one day, traditionally a strip 1 furlong (660 ft) by 1 chain (66 ft). Despite metric adoption in many fields, the acre persists in property records throughout the US and UK. A standard American football field (excluding end zones) is about 1.32 acres. The largest US state, Alaska, contains about 365 million acres. The acre relates to the square foot (43,560 ft² = 1 acre), the hectare (1 ha ≈ 2.471 acres), the square mile (640 acres = 1 mi²), and the square meter (1 acre ≈ 4,047 m²). US farms average around 446 acres, and the average UK farm is about 215 acres.
- US farmland and ranches
- UK rural property and estates
- Canadian rural property (legal survey system)
A US suburban lot is 0.25–0.5 acre. A standard UK rural property might be 5 acres. A football pitch is about 1.8 acres.
What is the Square Yard?
The square yard equals exactly 0.83612736 square meters (or 9 square feet) and is used for American and British carpet, fabric, landscaping, and small construction projects. Carpet pricing in the US has historically been per square yard, though many retailers now also quote per square foot. Lawn-fertilizer applications and grass-seed coverage often specify rates per 1,000 yd². The square yard relates to the square foot (9 ft² = 1 yd²), the square meter (1 yd² ≈ 0.836 m²), and the acre (4,840 yd² = 1 acre). Despite the prevalence of square feet in real estate and construction, the square yard remains entrenched in textile and landscaping commerce. A typical bedroom carpet is 12–20 square yards.
- Carpet and flooring orders (US and UK)
- Landscaping turf and sod
- Older UK property descriptions
A standard US bedroom is about 15 yd² of floor. Turf sod typically sold by the square yard.
