Both centimeter (cm) and decimeter (dm) are units of length in the Metric System. So when you convert between these units, you are performing a conversion between two units within the Metric System.

Let's take a closer look at the conversion formulas so that you can do these conversions yourself either with a calculator or with an old-fashioned pencil and paper.

The formula to convert from cm to dm is:

dm = cm x 0.1

The formula to convert from dm to cm is:

cm = dm x 10

Next, let's look at some examples showing the work and calculations that are involved in converting between centimeters (cm) and decimeters (dm).

Task: Convert 24 centimeters to decimeters (show work)Formula:cm x 0.1 = dmCalculations:24 cm x 0.1 = 2.4 dmResult:24 cm is equal to 2.4 dm

Task: Convert 53 decimeters to centimeters (show work)Formula:dm x 10 = cmCalculations:53 dm x 10 = 530 cmResult:53 dm is equal to 530 cm

For quick reference purposes, below are conversion tables that you can use to convert from cm to dm, and dm to cm.
