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.
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.
