Units explained
Square Centimeter
A square centimeter is a metric unit of area equal to 10⁻⁴ m² (1 cm × 1 cm). It is widely used in everyday measurement, lab work, and small-area applications.
Derived by squaring the centimeter (1/100 of a meter). The centi- prefix comes from the Latin 'centum' (hundred).
Square centimeters express the cross-sectional area of pipes and cables, the surface area of small everyday objects, biological tissue samples, and many engineering quantities. The SI unit for medical/pharmaceutical dose-per-area is often expressed in cm².
Centimeter has been part of the metric system since 1795.
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 cm² to katha:
1 × 1.494992e-6 = 1.494992e-6 katha
Example 2 — Convert 100 cm² to katha:
100 × 1.494992e-6 = 0.0001494992 katha
Real-world example — Hair-width scale measurements
A 70-square centimeter measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like kathas for direct comparison across supplier datasheets.
70 cm² × 1.494992e-6 = 0.0001046494 katha
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 square centimeters), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 cm² × 1.494992e-6 = 4.484975e-6 katha
Real-world example — Plastic-film thickness alternates
A 150-square centimeter plastic film converts cleanly to kathas — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 cm² × 1.494992e-6 = 0.0002242488 katha
