Units explained
Bigha (Kachha, North India)
A kachha (smaller) bigha is a traditional unit of land area used in North India, equal to approximately 1008 m² (about 0.25 acre). Used alongside the pucca bigha in Uttar Pradesh and Bihar.
The 'kachha' (raw or smaller) bigha is exactly one-third the size of the pucca bigha. Both units coexist in regional usage.
Kachha bighas appear in informal property descriptions and traditional land records in Uttar Pradesh and Bihar. Modern legal documents typically use hectares or pucca bighas with explicit conversion.
Traditional unit; relationship to pucca bigha standardized as 1:3.
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.
