Units explained
Square Foot
A square foot is an imperial unit of area equal to exactly 0.09290304 m². It is the dominant unit for real estate area measurement in the United States and is widely used in India for residential property listings.
Derived by squaring the foot. The foot was standardized to exactly 0.3048 m via the 1959 International Yard and Pound Agreement.
Square feet are the standard unit for US real estate floor area, HVAC capacity ratings (BTU per ft²), commercial leasing, and construction. In India, square feet is the dominant unit for residential property advertisements alongside traditional regional units.
