Because area is length squared, its conversion factors are the square of the equivalent length factors — a foot is 0.3048 meters, so a square foot is 0.3048² ≈ 0.0929 square meters. The acre is the odd one out: it's a historical land-measurement unit (originally the area a yoke of oxen could plow in a day) rather than a clean multiple of any other unit here.
