Units explained
Square Pole
A square pole is identical to a square rod, equal to approximately 25.293 m². 'Pole' is a regional name used in some US and British contexts.
Identical to square rod and square perch; differs only in regional naming preference.
Square poles appear in some historical US land records, particularly in mid-Atlantic states with strong English colonial heritage.
Standardized via the 1959 International Yard and Pound Agreement.
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.
