# Millimeters to Centimeters Conversion

Enter the length in millimeters below to get the value converted to centimeters.

Results in Centimeters: 1 mm = 0.1 cm

## How to Convert Millimeters to Centimeters To convert a millimeter measurement to a centimeter measurement, divide the length by the conversion ratio. One centimeter is equal to 10 millimeters, so use this simple formula to convert:

centimeters = millimeters ÷ 10

The length in centimeters is equal to the millimeters divided by 10.

For example, here's how to convert 5 millimeters to centimeters using the formula above.
5 mm = (5 ÷ 10) = 0.5 cm

Our inch fraction calculator can add millimeters and centimeters together and it also automatically converts the results to US customary, imperial and SI metric values.

## Millimeters

One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10-3. Millimeters can be abbreviated as mm, for example 1 millimeter can be written as 1 mm.

Millimeters are often represented by the smallest ticks on most metric rulers. To get a reference point of the size, the thickness of a US dime is 1.35mm.

## Centimeters

One centimeter is equal to one-hundredth (1/100) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The centimeter, or centimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "centi" is the prefix for 10-2. Centimeters can be abbreviated as cm, for example 1 centimeter can be written as 1 cm.

Metric rulers typically have 30 cm, which are represented by 30 large tick marks. To get a rough idea of the actual length of a centimeter, a standard pencil is just about 1cm thick.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
