About these units
Centimeter
The centimeter (0.01 meter) has been part of the CGS (centimeter-gram-second) system since the 19th century. Though the SI system prefers the meter, the centimeter remains widely used for everyday measurements in most countries.
Millimeter
The millimeter (0.001 meter) is particularly useful in precision engineering, optics, and manufacturing where sub-centimeter accuracy is required. It has been part of the metric system since its inception in France in the 1790s.
