Both decimeter (dm) and kilometer (km) 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 dm to km is:

km = dm x 0.0001

The formula to convert from km to dm is:

dm = km x 10,000

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

Task: Convert 45,000 decimeters to kilometers (show work)Formula:dm x 0.0001 = kmCalculations:45,000 dm x 0.0001 = 4.5 kmResult:45,000 dm is equal to 4.5 km

Task: Convert 18 kilometers to decimeters (show work)Formula:km x 10,000 = dmCalculations:18 km x 10,000 = 180,000 dmResult:18 km is equal to 180,000 dm

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