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.
Foot dates to ancient civilizations; modern exact value standardized in 1959.
Square Link
A square link is an imperial unit of area equal to approximately 0.0405 m². It is part of the chain-link surveying system used historically for land measurement.
Derived by squaring the link (1/100 of a chain = 7.92 inches). The Gunter's chain was introduced by English mathematician Edmund Gunter in 1620 for land surveying.
Square links appear in historical land surveys and legacy property records, particularly in the US Public Land Survey System (PLSS). Modern surveys use feet or meters instead.
Gunter's chain introduced in 1620; standardized via the 1959 International Yard and Pound Agreement.
