# Centimeters to Decimeters Converter

Use this converter to easily convert between Centimeters and Decimeters (cm to dm).

## How many Centimeters equal one Decimeter?

The centimeter and the decimeter are metric units that measure length. The abbreviation of centimeter is **cm**, and that of decimeter – **dm**. The metric system being based on multiples of 10, makes it truly easy to remember the connection between the different units. In this case a centimeter is 1 x 10^{-1} dm, or put simply – **1 decimeter is equal to 10 cm**, so there are **10 cm in one decimeter**.

## Difference between Centimeters and Decimeters

Both of these units are derived from the basic measurement unit of the metric system as established by the SI – the meter. It is defined as being equivalent to the length of the path that light travels is 1/299,792,458 seconds in vacuum.

The centimeter is 0.01 of the magnitude of a meter. It is a commonly used unit that allows people to perform tasks with precision, yet not making the whole ordeal way too complicated or difficult. Some of the applications one may find of a cm include measuring rainfall levels and taking measures for clothes.

The decimeter, on the other hand, is not too popular as a term. It is 1/10 of a meter, or 10 times the magnitude of a cm. The wavelength of the lowest UHF radio frequency, that is 300 GHz, is equal to 10 dm, and that of the highest frequency – 3 GHz, is only 1 dm. The most popular unit of volume – the liter – is equivalent to one cubic dm.

## How to convert Centimeters to Decimeters

In order to convert centimeters to decimeters you need to use the formula:

**cm / 10 = dm**,

or just shift the decimal point in the cm one position to the left.

#### Cm to dm conversion example
