Millimeters to cm Conversion Factor

The millimeter to cm conversion factor is 0.1

To find how many millimeters are there in a centimeter, just multiply the quantity in millimeters by 0.1.

You can also use the formula to convert from millimeters to cm below:

Value in centimeters = value in millimeters × 0.1

Examples:

Convert half millimeter to centimeters:
half millimeters = 0.5 × 0.1 = 0.05 centimeters.

Convert a millimeter to centimeters:
a millimeter = 1 × 0.1 = 0.1 centimeters.

Convert two millimeters to centimeters:
two millimeters = 2 × 0.1 = 0.2 centimeters.

Note: All values are rounded to 3 significant figures.

Convert three millimeters to centimeters three millimeters = 3 × 0.3 = 0.3 centimeters.

Convert 4 millimeters to centimeters 4 millimeters = 4 × 0.4 = 0.4 centimeters.

Convert half millimeter to centimeters half millimeters = 0.5 × 0.05 = 0.05 centimeters.

Convert a quarter millimeter to centimeters a quarter millimeters = 0.25 × 0.025 = 0.025 centimeters.

Convert one-fifth millimeter to centimeters one-fifth millimeters = 0.2 × 0.02 = 0.02 centimeters.

Convert one-eighth millimeter to centimeters one-eighth millimeters = 0.125 × 0.0125 = 0.0125 centimeters.

Definition of Centimeter

A centimeter (cm) is a decimal fraction of the meter, the International System of Units (SI) unit of length, approximately equivalent to 0.39 inches. The centimeter (cm) is a unit of length that was previously the base unit of length in the centimeter-gram-second (CGS) system of units. Although SI prefixes for factors of 103 are preferred by technicians, the centimeter remains a practical unit of length for everyday measurements. An average adult person's fingernail width is approximately equal to one centimeter, making it useful for measuring small objects or distances.
