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 Furlong
A square furlong is an imperial unit of area equal to exactly 40,468.564 m², or 10 acres.
Derived by squaring the furlong (660 feet or 1/8 mile). The furlong itself comes from medieval English 'furrow long', the length of a plowed furrow.
Square furlongs are rarely used today. The unit appears occasionally in historical English farming records and in some horseracing contexts (though usually as length, not area).
Medieval English origin; standardized via the 1959 International Yard and Pound Agreement.
