## What Is a Centimeter?

A centimeter is a unit used to measure length.

The centimeter, or centimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "centi" is the prefix for hundredths, or 10-2. Centimeters can be abbreviated as cm; for example, 1 centimeter can be written as 1 cm.

Metric rulers typically have 30 cm, which are represented by 30 large tick marks. To get a rough idea of the actual length of a centimeter, a standard number 2 pencil is just about 1 cm thick.

## How Long Is a Centimeter?

One centimeter is equal to one-hundredth (1/100) of a meter, which is defined as the distance light travels in a vacuum in 1/299,792,458 of a second. One centimeter is equal to 0.393701 inches.

## How to Convert Centimeters

To convert centimeters to another unit of length, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for centimeters in the conversion table below.

Then, multiply the length measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

centimeters × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
