What is a millimeter?
A millimeter is one thousandth of a meter, and ten millimeters make one centimeter. It is the unit engineers, machinists, and builders reach for when a fraction of a centimeter would be too rough.
A credit card is about 0.8 mm thick and a standard pencil lead is 0.7 mm across. Rainfall, screw sizes, plywood thickness, and phone dimensions are all usually given in millimeters.
In writing, the millimeter is usually shortened to "mm". One millimeter is 0.001 meters, and that ratio is what every figure on this page is built from.
