The centimeter and the millimeter are both units of length derived from the meter. The meter is the base unit of length in the International System of Units (the modern form of the metric system and the most widely used system of measurement in the world). The prefix "centi-" means one hundredth, so 1 centimeter is equivalent to one hundredth of a meter (0.01 meters). The prefix "milli-" means one thousandth, so 1 millimeter is equivalent to one thousandth of a meter (0.001 meters). The conversion factor (10) makes it easy to convert from one unit of measurement (400 centimeters in this case) to another (millimeters) while maintaining the accuracy of length conversions.
