How to Convert Nanometer to Micrometer

To convert from Nanometer (nm) to Micrometer (µm), multiply the value by 0.001.

Formula: µm = nm × 0.001

Reverse: nm = µm × 1,000

Step-by-Step Example

Start with your value in Nanometer. For example: 5 nm
Multiply by the conversion factor: 5 x 0.001
The result is: 0.005 µm

About Nanometer

The nanometre equals one billionth of a metre and is the standard scale for wavelengths of light and semiconductor process nodes.

Common uses: optics, chip manufacturing, nanotechnology.

About Micrometer

The micrometre (micron) equals one millionth of a metre. It is the working scale of cells, machining tolerances and airborne particulates.

Common uses: microscopy, machining tolerances, air quality (PM).
