Centimeter / Millimeter Units Definition
Centimeter
The centimeter is in common popular use: it allows to represent in a simple way dimensions of human size (less than the meter).In the scientific field, we prefer the meter (base unit of the International System) or the millimeter (widely used in mechanics) to represent lengths of these orders of magnitude.
Millimeter
The millimeter mm (thousandth of a meter, 10-3m). It is difficult to manipulate with your fingers an object smaller than 1mm. The micrometer or micron µm (thousandth of a mm, 10-6m): the thickness of soap bubbles, when they make pretty colors, is a few microns.
