About Square Centimeters
A square centimeter (cm²) is a metric unit of area equal to a square with sides of one centimeter (10 mm × 10 mm). It is widely used for measuring moderate-sized surfaces like postage stamps, credit cards, or smartphone screens. A standard credit card has an area of about 46 cm². This unit is common in everyday crafts, school science, and smaller construction projects where precision matters but square meters would be too large.
