What Is a Centiliter?

Centimeter is a unit of measurement of length, equal to one hundredth of a meter. Unit of length, the English symbol is abbreviated as: cm., 1 cm = 1/100 meters. 1cm (cm) = 10mm (mm) = 0.1dm (dm) = 0.01m (m).

Centimeter, unit of length, abbreviated (symbol): cm.

Conversion in units of centimeters: 1 cm = 10 mm = 10000

The unit of length is measurement

Is centimeter an international unit? Chen Liqi discussed it with his colleagues during the teaching process. This topic is due to the lack of a systematic introduction to the knowledge of the international unit system in the middle school physics textbooks and the general physics textbooks at hand of middle school physics teachers. The answers differ widely. Some colleagues think that centimeters are not international units, because their teachers taught them when they were studying in middle school or university, which prompted me to more urgently want to know exactly what to avoid to spread the word. Chen Liqi consulted the relevant information and compiled the following text for reference only.

(1) Seven SI basic units. That is, the unit of length is meter, the unit of mass is kilogram, the unit of time is second, the unit of current is ampere [ampere], the unit of thermodynamic temperature is [Kelvin], the unit of quantity of substance is mole, and the unit of luminous intensity is [cancel].

(2) 2 auxiliary units of SI system. That is, flat angle unit radians and solid angle unit spheres.

It can be seen that the International System of Units has selected seven independent quantities as the basis. The first is the length. Its base unit name is meters and its symbol is m. The meter is the name of the SI basic unit of length. Units of physical quantities such as length, width, thickness, radius, perimeter, and distance are all expressed in meters or decimal units. And centimeters are not international units. ^[3]
