Decimeters to Kilometers (dm to km) Converter

How to convert decimeters to kilometers

Formulakm = dm × 0.0001

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

A decimeter is smaller than a kilometer: it takes 10,000 decimeters to make one kilometer.

About the units

Decimeter (dm)

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

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).

Frequently asked questions

How many kilometers are in one decimeter?

There are 0.0001 kilometers in one decimeter, and this value is exact by definition.

How do I convert decimeters to kilometers?

Multiply the number of decimeters by 0.0001. For example, 10 dm × 0.0001 = 0.001 km.

How many decimeters are in one kilometer?

One kilometer equals 10,000 decimeters. That is the reverse factor, 1 ÷ 0.0001.

What is 10 decimeters in kilometers?

10 dm = 0.001 km.

Is this dm to km 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.
