cm to Nanometers Converter (cm to nm)

How to convert centimeters to nanometers

Formulanm = cm × 10,000,000

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

A centimeter is larger than a nanometer: one centimeter contains 10,000,000 nanometers.

About the units

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).

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 centimeter?

There are 10,000,000 nanometers in one centimeter, and this value is exact by definition.

How do I convert centimeters to nanometers?

Multiply the number of centimeters by 10,000,000. For example, 10 cm × 10,000,000 = 100,000,000 nm.

How many centimeters are in one nanometer?

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

What is 10 centimeters in nanometers?

10 cm = 100,000,000 nm.

Is this cm 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.
