Decimeters to Micrometers (dm to µm) Converter

How to convert decimeters to micrometers

Formulaµm = dm × 100,000

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

A decimeter is larger than a micrometer: one decimeter contains 100,000 micrometers.

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).

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).

Frequently asked questions

How many micrometers are in one decimeter?

There are 100,000 micrometers in one decimeter, and this value is exact by definition.

How do I convert decimeters to micrometers?

Multiply the number of decimeters by 100,000. For example, 10 dm × 100,000 = 1,000,000 µm.

How many decimeters are in one micrometer?

One micrometer equals 0.00001 decimeters. That is the reverse factor, 1 ÷ 100,000.

What is 10 decimeters in micrometers?

10 dm = 1,000,000 µm.

Is this dm to µm 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.
