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 Hectometer
A square hectometer is a metric unit of area equal to 10,000 m². It is identical in value to the hectare.
Derived by squaring the hectometer (100 m). The hecto- prefix comes from the Greek 'hekaton' (hundred).
Functionally equivalent to hectares. In contexts where the prefix system is preferred over the special name 'hectare', hm² may be used.
Hectometer has been part of the metric system since 1795.
