Units explained
Bigha (Pucca, North India)
A pucca (full) bigha is a traditional unit of land area used in North India, equal to approximately 3025 m² (about 0.75 acre). Used in Uttar Pradesh, Bihar, Uttarakhand, and parts of Madhya Pradesh.
Originated as a traditional Indian agricultural land measure. The 'pucca' (literally 'cooked' or 'full') bigha distinguishes it from the 'kachha' (raw or half) bigha, which is one-third as large.
Pucca bighas appear in land records, property deeds, and agricultural statistics across North India. The exact size can vary between districts; 3025 m² is the most common standardized value in Uttar Pradesh.
Traditional unit; standardized in different ways by different state governments over time.
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.
