Units explained
Kanal
A kanal is a unit of land area used in Punjab, Haryana, and Pakistani Punjab, equal to approximately 505.857 m² (1/8 of an acre or 605 square yards).
Defined as 1/8 of an acre during British colonial administration of Punjab. 8 kanals make 1 acre; 20 marlas make 1 kanal.
Kanals are the primary unit for residential property in Punjab (India and Pakistan), Haryana, Jammu and Kashmir, and Himachal Pradesh. Property listings typically use kanal and marla units alongside square feet.
Standardized in colonial Punjab.
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.
