Convert Micrometers to nanometers
1 micrometer = 1,000 nanometers · nm = µm × 1,000
When you need this conversion
This conversion goes from micrometers, used for manufacturing tolerances and filtration ratings, to nanometers, the scale of semiconductors and light wavelengths. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.

The formula
nm = µm × 1,000Because both units measure length, the conversion is a single multiplication by a fixed factor. That factor never changes, so the result is exact.
