Units explained
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.
Square Meter
A square meter is the SI base unit of area, defined as the area of a square with sides of one meter. It is the universal scientific unit for area.
Defined by squaring the meter, which was redefined in 2019 in terms of the speed of light. The meter itself was originally proposed by the French Academy of Sciences in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Square meters are the universal SI unit for area, used in real estate (most countries outside the US/UK), construction, physics, engineering, materials science, biology, and nearly all scientific contexts worldwide.
Meter adopted as SI base unit in 1960; current exact definition via speed of light dates to 2019.
