Standardized via the 1959 International Yard and Pound Agreement.
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.
