A square centimeter (cm²) is a unit of area in the metric system. It represents the area of a square with each side measuring one centimeter. This measurement is commonly used in various fields, including science, engineering, and everyday life, to quantify small areas, such as the size of a piece of paper or a small garden plot. To visualize a square centimeter, imagine a square that is 10 millimeters on each side, as there are 10 millimeters in a centimeter. Square centimeters are often used in conjunction with other metric units, such as square meters or square millimeters, to provide a comprehensive understanding of area measurements.
