Kilometers to Decimeters (km to dm) Converter

How to convert kilometers to decimeters

Formuladm = km × 10,000

Multiply the value in kilometers by 10,000. To go the other way, multiply by 0.0001 (or divide by 10,000).

A kilometer is larger than a decimeter: one kilometer contains 10,000 decimeters.

About the units

Kilometer (km)

One thousand metres. Kilometres measure road distances and running races in most countries; a 10K race is 10 km, about 6.2 miles. One kilometer equals 1,000 meters (m).

Decimeter (dm)

The decimeter (dm) is a unit of length in the International System of Units (SI). One decimeter equals 0.1 meters (m).

Frequently asked questions

How many decimeters are in one kilometer?

There are 10,000 decimeters in one kilometer, and this value is exact by definition.

How do I convert kilometers to decimeters?

Multiply the number of kilometers by 10,000. For example, 10 km × 10,000 = 100,000 dm.

How many kilometers are in one decimeter?

One decimeter equals 0.0001 kilometers. That is the reverse factor, 1 ÷ 10,000.

What is 10 kilometers in decimeters?

10 km = 100,000 dm.

Is this km to dm converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
