Definition: The square centimeter is a metric area unit based on a 1 cm by 1 cm square. Because 100 centimeters make a meter, 10,000 cm² fit inside one square meter.

Current use: Cm² is often used for labels, small panels, craft materials, skin or wound measurements, classroom area problems, and compact surfaces measured with a centimeter ruler.
