Units explained
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.
Katha (Bengal)
A Bengal katha is a traditional unit of land area equal to approximately 66.89 m² (1/20 of a Bengal bigha or 720 square feet). Used in West Bengal and Bangladesh.
Defined as 1/20 of the Bengal bigha during colonial standardization.
Bengal kathas are widely used in residential property descriptions in Kolkata, Dhaka, and other Bengali-speaking regions. Property advertisements often list area in kathas with chatak (1/16 katha) subdivisions.
Standardized in colonial Bengal.

Worked examples
Example 1 — Convert 1 m² to katha:
1 × 0.0149499178 = 0.0149499178 katha
Example 2 — Convert 100 m² to katha:
100 × 0.0149499178 = 1.4949917775 katha
Real-world example — Fabric purchase length
Two square meters of fabric equals a value in kathas essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 m² × 0.0149499178 = 0.0298998356 katha
Real-world example — Maritime depth conversion
A 10-square meter sounding depth converts cleanly into kathas. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 m² × 0.0149499178 = 0.1494991778 katha
Real-world example — Reference scenario in case of fallback
Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.
1 m² × 0.0149499178 = 0.0149499178 katha
