Feet to square feet, and property units

Feet to square feet is a common search but not a unit conversion: square feet is length × width. A room 12 ft by 10 ft is 120 sq ft, which the converter above turns into 11.15 sq m or 13.33 gaj. Gaj in property listings means square gaj, which equals a square yard (9 sq ft). A 100 gaj plot is 900 sq ft or 83.6 sq m. Cent is a hundredth of an acre (435.6 sq ft), used in Kerala, Tamil Nadu and Karnataka. Ground is 2,400 sq ft, used in Chennai. Guntha is 1,089 sq ft (a fortieth of an acre), used in Maharashtra, Gujarat and Karnataka. Bigha and biswa vary by state and are not included, since a single factor would be wrong for most readers.
