Nanometers to Micrometers converter

To convert nanometers to micrometers, enter the value in the first field. The result in micrometers is calculated automatically using the exact conversion factor.

1 nm = 0.001 µm
1 µm = 1000 nm

Formula: µm = nm × 0.001
nm = µm × 1000

Definitions: 1 nm = 1 × 10^-9 m; 1 µm = 1 × 10^-6 m

The nanometer (nm) is one billionth of a meter. It is the unit for wavelengths of light (visible light spans roughly 400 to 700 nm), for features on semiconductor chips and for the size of viruses and molecules.

The micrometer (µm), also called a micron, is one millionth of a meter. It is used for the thickness of thin films and fibers, for the size of bacteria, cells and dust particles, and for filter ratings (PM2.5 and PM10 count particles up to 2.5 and 10 µm).
