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.
Decimal (Indian)
A decimal (Indian usage) is a unit of land area equal to 1/100 of an acre, or approximately 40.4686 m². It is identical to the cent but uses the term 'decimal' in Bengal and Bangladesh.
Same definition as the cent; the regional naming differs. 'Decimal' is preferred in West Bengal, Bangladesh, and some Northeast Indian states.
Decimals appear in property listings, agricultural records, and land documents in Bengal and Bangladesh. The term coexists with bigha (which is much larger) and katha for everyday use.
Standardized in colonial Bengal.
