Micrometers to Decimeters (µm to dm) Converter

How to convert micrometers to decimeters

Formuladm = µm × 0.00001

Multiply the value in micrometers by 0.00001. To go the other way, multiply by 100,000 (or divide by 0.00001).

A micrometer is smaller than a decimeter: it takes 100,000 micrometers to make one decimeter.

About the units

Micrometer (µm)

One millionth of a metre, often called a micron. Human hair is roughly 50–100 µm across, and filter and particle sizes are given in micrometres. One micrometer equals 0.000001 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 micrometer?

There are 0.00001 decimeters in one micrometer, and this value is exact by definition.

How do I convert micrometers to decimeters?

Multiply the number of micrometers by 0.00001. For example, 10 µm × 0.00001 = 0.0001 dm.

How many micrometers are in one decimeter?

One decimeter equals 100,000 micrometers. That is the reverse factor, 1 ÷ 0.00001.

What is 10 micrometers in decimeters?

10 µm = 0.0001 dm.

Is this µm 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.
