# Centimeter (cm)

A centimeter (cm) is a unit of length in the metric system. One cm is equal to one hundredth (1/100) of a meter, or one thousandth (1/1000) of a kilometer. The centimeter is a unit of measurement in the International System of Units (SI), and is the base unit of length in the SI units of measurement. How do you write cm? The answer is that there is no standard way to write cm. However, the most common way to write cm is to use the abbreviated form, cm.

#### What is cm example?

The International Organization for Standardization (ISO) uses the International System of Units (SI) to define the meter, and thus the centimeter. The meter is currently defined as the distance light travels in a vacuum in 1/299,792,458 seconds. This definition was adopted in 1983 by the 17th General Conference on Weights and Measures.

One centimeter is one hundredth of a meter, or equivalently, one thousandth of a kilometer. The centimeter was first introduced in 1795 by French mathematician and physicist, Gabriel Mouton. It was adopted by the 9th General Conference on Weights and Measures in 1889.

The SI unit prefix "centi-" represents a factor of 10-2, or one hundredth. Thus, one centimeter can be written as 1 cm, or 0.01 m. What makes up 1 cm? There are various definitions of a centimeter. The International System of Units (SI) defines the centimeter as 1/100th of a meter. In other systems, the centimeter is 1/10th of a decimeter, 1/1000th of a kilometer, or 1/100000th of a megameter.

### Which is bigger cm or mm?

The answer to this question depends on the context in which it is being asked. In general, cm stands for "centimeter" and mm stands for "millimeter." However, there are some cases in which mm can stand for "megameter."

In most cases, a cm is bigger than a mm. For example, a sheet of paper is typically about 10 cm wide and 1 mm thick. However, there are some cases in which a mm is bigger than a cm. For example, a kilometer is 1000 meters, or 100,000 cm, while a megameter is one million meters, or 100,000,000 cm. So in this context, a mm is 1000 times bigger than a cm. How many inches is 1 cm in inches? There are 2.54 centimeters in an inch, so 1 cm in inches is equal to 1/2.54 = 0.3937 inches.
