Units explained
Square Kilometer
A square kilometer is a metric unit of area equal to 1,000,000 m² (one million square meters), or 100 hectares. It is used for measuring large land areas, regional geography, and country-scale statistics.
Derived by squaring the kilometer (1000 m). The kilo- prefix comes from the Greek 'chilioi' (thousand).
Square kilometers express the area of cities, districts, lakes, forests, and entire countries. India's total area is approximately 3,287,263 km². 1 km² equals 100 hectares or about 247.105 acres.
Kilometer has been part of the metric system since 1795.
Square Rod
A square rod is an imperial unit of area equal to approximately 25.293 m². It is part of the historical English land survey system.
Derived by squaring the rod (16.5 feet or 1/4 chain). The rod, perch, and pole are three names for the same length.
Square rods appear in historical English and American land surveys and legacy property records. The unit is largely obsolete today, surviving mainly in legal descriptions of older land grants.
Standardized via the 1959 International Yard and Pound Agreement.
