What is a centimeter?
A centimeter is one hundredth of a meter, so 100 centimeters make one meter. It is the unit most rulers show, and it is the standard way to give a person's height or a package's size in metric countries.
For a quick mental picture: your little finger is roughly one centimeter wide, and a new pencil is about 19 centimeters long. Centimeters sit close to inches in size, which is why the cm-to-inch conversion is one of the most searched of all.
In writing, the centimeter is usually shortened to "cm". One centimeter is 0.01 meters, and that ratio is what every figure on this page is built from.
