What is a square millimeter?
A square millimeter is a tiny square one millimeter on each side; a million of them make one square meter. It is about the size of a pinhead.
Engineers and machinists use it for wire cross-sections, small components and tolerances, and biologists use it under the microscope.
In writing, the square millimeter is usually shortened to "mm²". One square millimeter is 0.000001 square meters, and that ratio is what every number on this page is built from.
