Millimeters (mm) to Centimeters (cm) Conversion
Millimeters
The millimetre is a unit of length equal to one thousandth of a metre (10⁻³ m), derived using the SI prefix milli- (from Latin mille, thousand). It is the standard unit for precision measurements in engineering, manufacturing, and medicine, where tolerances are routinely specified to the nearest millimetre or fraction thereof. In meteorology, rainfall is universally measured in millimetres, where 1 mm of rainfall corresponds to 1 litre of water per square metre of surface area.
Centimeters
The centimetre is a unit of length equal to one hundredth of a metre (10⁻² m), derived using the SI prefix centi- (from Latin centum, meaning hundred). It is widely used in everyday measurement of body height, garment sizing, and small objects, and is the standard unit in medicine, tailoring, and interior design. In the CGS (centimetre-gram-second) system that preceded modern SI, the centimetre served as the fundamental unit of length, giving rise to derived units such as the dyne and erg still encountered in physics literature.
