Units explained
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.
Bigha (Assam)
An Assam bigha is a traditional unit of land area used in Assam and parts of Northeast India, equal to approximately 1337.8 m² (functionally identical to the Bengal bigha).
Derived from the same colonial Bengali standardization that produced the Bengal bigha. Assam land records share much of Bengal's traditional unit system.
Assam bighas are used in property transactions and agricultural records across Assam and several other Northeast states. The unit equals 14,400 sq ft.
Standardized in colonial Bengal/Northeast India administration.
