Key Difference: Mm is equal to one thousandth of a meter, while cm is equal to one hundredth of a meter. These are both unit of measurement.

Millimeters and centimeters are common words that are heard when trying to measure something. They are a unit of measurement in the international metric system. Millimeter (mm) and centimeter (cm) are a unit of length and are associated with the International System of Units base unit, meter.

The metric system is an international decimalized system of measurement that was based on the French mètre des archives and the kilogramme des archives. Over the years, this system has been refined and has also incorporated additional measuring units. Currently, it has become the official system of measurement in almost every country, with only a few select countries that have not yet adopted the system. These countries include Liberia, Burma and the United States. The meter is the fundamental unit of length in the SI. It was originally intended to be the one-ten-millionth of the distance from the Earth’s equator to the North Pole, but was later revised. Since 1983, the 17th General Conference on Weight and Measurement claim it to be as "the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second.”

The millimeter (mm) is a unit of length in the metric system and is equal to one thousandth of a meter. It is also equal to 0.1 centimeter, 1,000 micrometres and 1,000,000 nanometres. Similar to mm, the centimeter is also a unit of length in the metric system and is equal to one hundredth of a meter. 1 centimeter is equal to 10 millimeter, 10,000 micrometers and 10,000,000 nanometers.
