Micrometers to Nanometers Converter

1 micrometer (µm) equals 1,000 nanometers (nm).

Quick answer

1 micrometer = 1,000 nanometers
1 nanometer = 0.001 micrometers
Formula: nm = µm × 1,000

From To 1,000

1 micrometer = 1,000 nanometers

How to convert micrometers to nanometers

nm = µm × 1,000

To convert micrometers to nanometers, multiply the number of micrometers by 1,000.

Example: 18 µm to nm

Start with the value in micrometers: 18 µm.
Multiply by 1,000: 18 × 1,000 = 18,000.
Result: 18 micrometers = 18,000 nanometers.

Going the other way, 1 nanometer = 0.001 micrometers, so to convert nanometers back to micrometers you divide by the same number. See nanometers to micrometers.
