What is a Square Foot?

The square foot equals exactly 0.09290304 square meters and is the standard unit for American and British residential and commercial real estate. US apartments are advertised by total square footage (a typical 2-bedroom apartment is 800–1,200 ft²), and home-improvement projects (flooring, paint coverage, drywall) use square feet for material calculations. Commercial leases quote rates in dollars per ft² per year. The square foot is intuitive for human-scale spaces — a typical office cubicle is about 64 ft² (8 ft × 8 ft). It relates to the square meter (1 ft² ≈ 0.0929 m²), the square yard (9 ft² = 1 yd²), the square inch (144 in² = 1 ft²), and the acre (43,560 ft² = 1 acre). Outside the US and UK, square meters dominate; within them, the square foot is the everyday property unit.
