Units explained
Arpent (Canadian)
A Canadian arpent is a historical unit of area equal to exactly 3418.89 m². Used in French-Canadian land records, especially in Quebec and Louisiana.
Standardized in French colonial Canada at 100 perches squared, the perche being the Canadian standard of 18 French pieds.
Canadian arpents appear in legal land descriptions in Quebec, where they remain officially recognized for historical seigneurial properties. Also appear in Louisiana land records from the French colonial period.
French colonial Canadian/Louisiana origin; remains in legal use in Quebec for historical properties.
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.
