What is a square centimeter?
A square centimeter is a square one centimeter on each side — roughly the face of a small button or a fingernail. Ten thousand of them fit into one square meter.
It shows up in medicine for measuring skin areas and wounds, in electronics for chip sizes, and anywhere small surfaces need a precise figure.
In writing, the square centimeter is usually shortened to "cm²". One square centimeter is 0.0001 square meters, and that ratio is what every number on this page is built from.
