Nanometers to mm Converter (nm to mm)

How to convert nanometers to millimeters

Formulamm = nm × 0.000001

Multiply the value in nanometers by 0.000001. To go the other way, multiply by 1,000,000 (or divide by 0.000001).

A nanometer is smaller than a millimeter: it takes 1,000,000 nanometers to make one millimeter.

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).

Millimeter (mm)

One thousandth of a metre. Millimetres are the standard unit on engineering drawings, rulers and rainfall gauges; a credit card is about 0.76 mm thick. One millimeter equals 0.001 meters (m).

Frequently asked questions

How many millimeters are in one nanometer?

There are 0.000001 millimeters in one nanometer, and this value is exact by definition.

How do I convert nanometers to millimeters?

Multiply the number of nanometers by 0.000001. For example, 10 nm × 0.000001 = 0.00001 mm.

How many nanometers are in one millimeter?

One millimeter equals 1,000,000 nanometers. That is the reverse factor, 1 ÷ 0.000001.

What is 10 nanometers in millimeters?

10 nm = 0.00001 mm.

Is this nm to mm 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.
