Units explained
Carucate
A carucate was a medieval English unit of land area equal to approximately 485,623 m² (about 120 acres or 48.6 hectares).
Originated in early medieval England as the area one team of eight oxen could plow in a year. The size varied considerably by soil type and region.
Carucates appear in the Domesday Book and other medieval English land surveys. The unit was used for taxation assessment but was inherently variable due to its agricultural-output basis.
Anglo-Saxon English origin; obsolete by late medieval period.
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.
