How many millimeters are in one centimeter?

One centimeter is equivalent to 10 millimeters. This is based on the metric system, where the prefix "centi-" denotes a factor of one-hundredth. Therefore, one centimeter (which is 1/100 of a meter) can be subdivided into 10 millimeters, each of which is 1/1000 of a meter. Understanding this relationship is pivotal for converting between different metric units of length, which is frequently necessary in scientific measurements and calculations.
