Nanometers to Decimeters (nm to dm) Converter

How to convert nanometers to decimeters

Formuladm = nm × 1×10⁻⁸

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

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

About the units

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).

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 nanometer?

There are 1×10⁻⁸ decimeters in one nanometer, and this value is exact by definition.

How do I convert nanometers to decimeters?

Multiply the number of nanometers by 1×10⁻⁸. For example, 10 nm × 1×10⁻⁸ = 1×10⁻⁷ dm.

How many nanometers are in one decimeter?

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

What is 10 nanometers in decimeters?

10 nm = 1×10⁻⁷ dm.

Is this nm 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.
