Units explained
Morgen (Prussian)
A Prussian morgen was a historical German unit of area equal to approximately 2553.22 m².
Originated from the medieval German morgen, the area one man could plow in a morning. The Prussian morgen was standardized at 25,532 square Prussian feet.
Prussian morgens appear in historical German land records, particularly from the 18th and 19th centuries. Abolished in favor of metric units in 1872 with the German Empire's standardization.
Medieval German origin; abolished 1872.
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.
