Convert Millimeters to Centimeters
Learn How to Convert Millimeters to Centimeters Using our Conversion Formula
Converting a millimeter length measurement to a centimeter measurement involves multiplying your length by the conversion ratio to find the result. A millimeter is equal to 0.1 centimeters, so to convert simply multiply by 0.1.
For example, 5mm = (5 × 0.1) = 0.5cm.
Our inch fraction calculator can add millimeters and centimeters together and it also automatically converts the results to both imperial and metric values.

Millimeter is spelled millimetre internationally, and it is equal in length to .1 centimeters, 1000 micrometers, or 5/127 inch. They are represented by the smallest ticks on most metric rulers. To get a reference point of the size, the thickness of a dime is 1.35mm.
Internationally the centimeter is actually spelled centimetre and it's equal to 10 millimeters, .01 meters, or .393701 inches. Metric rulers have 30cm and they are the larger measurement. A standard pencil is just about 1cm thick, and can be used to get a rough idea of the size of a centimeter.
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.
