Nanometers to cm Converter (nm to cm)

How to convert nanometers to centimeters

Formulacm = nm × 1×10⁻⁷

Multiply the value in nanometers by 1×10⁻⁷. To go the other way, multiply by 10,000,000 (or divide by 1×10⁻⁷).

A nanometer is smaller than a centimeter: it takes 10,000,000 nanometers to make one centimeter.

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).

Centimeter (cm)

One hundredth of a metre. Centimetres are the everyday metric unit for body height, clothing sizes and small objects; a standard paper clip is about 3 cm long. One centimeter equals 0.01 meters (m).

Frequently asked questions

How many centimeters are in one nanometer?

There are 1×10⁻⁷ centimeters in one nanometer, and this value is exact by definition.

How do I convert nanometers to centimeters?

Multiply the number of nanometers by 1×10⁻⁷. For example, 10 nm × 1×10⁻⁷ = 0.000001 cm.

How many nanometers are in one centimeter?

One centimeter equals 10,000,000 nanometers. That is the reverse factor, 1 ÷ 1×10⁻⁷.

What is 10 nanometers in centimeters?

10 nm = 0.000001 cm.

Is this nm to cm 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.
