Units explained
Katha (Assam)
An Assam katha is a traditional unit of land area equal to approximately 269.71 m² (1/5 of an Assam bigha). It is larger than the Bengal katha despite sharing the name.
Defined as 1/5 of the Assam bigha. The same word 'katha' refers to different sizes in different regional systems.
Assam kathas appear in property records across Assam, particularly for agricultural and rural land transactions.
Traditional regional unit; relationship to bigha standardized as 1:5 in Assam.
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.
