Nanometers to Micrometers (nm to µm) Converter

How to convert nanometers to micrometers

Formulaµm = nm × 0.001

Multiply the value in nanometers by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).

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

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).

Micrometer (µm)

One millionth of a metre, often called a micron. Human hair is roughly 50–100 µm across, and filter and particle sizes are given in micrometres. One micrometer equals 0.000001 meters (m).

Frequently asked questions

How many micrometers are in one nanometer?

There are 0.001 micrometers in one nanometer, and this value is exact by definition.

How do I convert nanometers to micrometers?

Multiply the number of nanometers by 0.001. For example, 10 nm × 0.001 = 0.01 µm.

How many nanometers are in one micrometer?

One micrometer equals 1,000 nanometers. That is the reverse factor, 1 ÷ 0.001.

What is 10 nanometers in micrometers?

10 nm = 0.01 µm.

Is this nm to µm 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.
