Millimeters to centimeters conversion (mm to cm)

1 millimeter = 0.1 centimeters

Use the millimeters to centimeters converter below to convert your length measurements. Enter the number of millimeters and the converter will display its equivalent in centimeters.

To convert millimeters to centimeters, divide the length in millimeters by the conversion factor 10. So, to find out what is 1 millimeter in centimeters, the calculation is as follows: 1 millimeter ÷ 10 = 0.1 centimeters. Therefore, 1 millimeter is equal to 0.1 centimeters. From this answer, we can also deduce that there are 0.1 cm in 1 mm.

The conversion formula to convert millimeters to centimeters is as follows:

centimeters = millimeters ÷ 10

The prefix "milli-" means one thousandth, so 1 millimeter is equivalent to one thousandth of a meter (0.001 meters). The prefix "centi-" means one hundredth, so 1 centimeter is equivalent to one hundredth of a meter (0.01 meters).

The millimeter and the centimeter are both units of length derived from the meter. The meter is the base unit of length in the International System of Units (the modern form of the metric system and the most widely used system of measurement in the world). The conversion factor (10) facilitates the conversion from one unit of measurement (1 millimeter in this case) to another (in centimeters) while maintaining the accuracy of length conversions.

A length of 1 millimeter, measured with a ruler, vernier caliper, micrometer, or tape measure, often needs to be converted to centimeters in certain situations. Our conversion calculator is the fastest and most accurate option for converting 1 millimeter to centimeters. It can also be used to convert other dimensions, including size, width, height, small distances, thickness, and diameter.

The conversion table below provides length measurements in millimeters (mm) and their equivalents in centimeters (cm) for values ranging from 1 to 100 millimeters in increments of 1 millimeters.
