The following is a list of definitions relating to conversions between decimeters and kilometers.

A decimeter is a unit of length in the Metric System. The symbol for decimeter is dm. There are 10,000 decimeters in a kilometer. The International spelling is decimetre.

A kilometer is a unit of length in the Metric System. The symbol for kilometer is km. There are 0.0001 kilometers in a decimeter. The International spelling is kilometre.

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

The formula to convert from dm to km is:

km = dm ÷ 10,000

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 from decimeters to kilometers (dm to km) or converting from kilometers to decimeters (km to dm).

Task: Convert 45,000 decimeters to kilometers (show work)Formula:dm ÷ 10,000 = kmCalculations:45,000 dm ÷ 10,000 = 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
