Decimeters to Nanometers (dm to nm) Converter

How to convert decimeters to nanometers

Formulanm = dm × 100,000,000

Multiply the value in decimeters by 100,000,000. To go the other way, multiply by 1×10⁻⁸ (or divide by 100,000,000).

A decimeter is larger than a nanometer: one decimeter contains 100,000,000 nanometers.

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).

Nanometer (nm)

One billionth of a metre. Visible light wavelengths run from about 380 to 750 nm, and semiconductor process nodes are named in nanometres. One nanometer equals 1×10⁻⁹ meters (m).

Frequently asked questions

How many nanometers are in one decimeter?

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

How do I convert decimeters to nanometers?

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

How many decimeters are in one nanometer?

One nanometer equals 1×10⁻⁸ decimeters. That is the reverse factor, 1 ÷ 100,000,000.

What is 10 decimeters in nanometers?

10 dm = 1,000,000,000 nm.

Is this dm to nm 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.
