Units explained
Square Dekameter
A square dekameter is a metric unit of area equal to 100 m². It is identical in value to the are.
Derived by squaring the dekameter (10 m). The deca- prefix comes from the Greek 'deka' (ten).
Square dekameters are functionally equivalent to ares. In contexts where the prefix system is preferred, dam² may be used in place of 'are' for clarity.
Dekameter has been part of the metric system since 1795.
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.
