Centimeter To Millimeter(cm to mm) Conversion Calculator


What Is Centimeter (cm)?

A centimeter is a metric unit of length used to measure shorter distances and shorter lengths of objects. It is denoted using the symbol “cm”. It’s also the length unit in the International System of Units (SI), which is the current version of the metric system. The unit of centimeter is based upon the SI unit of a meter, and the prefix “centi” indicates that it is equivalent to one-hundredth of a meter. 

What Is Millimeter (mm)?

A millimeter is a metric unit of length equal to one-thousandth of a meter, which is the SI base unit of length. It is denoted using the symbol “mm”. As a result, a meter is made up of 1000 millimeters. A centimeter is made up of 10 millimeters. One millimeter is composed of 1000 micrometers or 1000000 nanometers. The millimeter is defined by the SI units, which are used in the international system of measures.

Just like cm, mm is also a commonly used metric that falls in the International System of Units (SI). In any ruler scale, the smallest unit of measurement is mm. 

Here are some common measurements that use the mm scale.

  • Width of human hair
  • Width of paper
  • Tumour sizes
  • Diameter of pen/pencil nibs
  • Width of CDs

How to Convert Centimeter (cm) To Millimeter (mm)?

To convert a centimeter to a millimeter, simply multiply the number of centimeters by ten. For example, to convert 5 centimeters to millimeters, simply multiply 5 by 10 and get 50. As a result, 5 cm equals 50 mm. This works because every 1 centimeter contains 10 mm. Converting centimeters to millimeters is also possible simply by changing the decimal one point to the right. For example, to convert 35.2 cm to mm, simply move the decimal one position to the right. As a result, 35.2 cm equals 352 mm.
