Micrometer to Nanometer Converter
Convert micrometers to nanometers (µm to nm) instantly with this free online length converter. Enter any value in the Micrometer field and get the equivalent in Nanometer immediately. This converter handles any quantity — from tiny fractions to large numbers — with full precision. No signup, no ads in the widget, and the conversion runs entirely in your browser for instant results.
The conversion factor is exact: 1 µm = 1000 nm. To convert micrometers to nanometers, multiply your Micrometer value by 1000. For example, 10 µm = 10000 nm. You can also reverse the calculation: 1 nm = 0.001 µm.
Quick conversion table
| Micrometer (µm) | Nanometer (nm) |

Formula
Micrometer to Nanometer conversion: 1 µm = 1000 nm nanometers = micrometers × 1000 1 nm = 0.001 µm micrometers = nanometers × 0.001
Example
Example: Convert 10 µm to nm: 10 µm × 1000 = 10000 nm So, 10 µm is about 10000 nm. To convert back, multiply by 0.001: 10000 nm × 0.001 = 10 µm.

Frequently Asked Questions
How do I convert micrometers to nanometers?
Enter the value in Micrometer (µm) in the 'From' field. The equivalent in Nanometer (nm) appears instantly in the 'To' field. The converter uses precise conversion factors and updates in real time as you type.
What is the formula to convert µm to nm?
1 µm = 1000 nm, so nanometers = micrometers × 1000. To convert back, 1 nm = 0.001 µm. The full formula and a worked example are shown on this page.
How many nanometers are in one Micrometer?
1 µm = 1000 nm.
Is this Micrometer to Nanometer converter free?
Yes, completely free with no signup, no limits, and no ads in the converter widget. You can convert as many values as you need. The tool runs entirely in your browser, so your data never leaves your device.
Can I convert nanometers back to micrometers?
Yes. Click the 'Swap Units' button to reverse the direction. You can also use the dropdown menus to select any other length unit for either field.
How accurate is the µm to nm conversion?
The converter uses high-precision conversion factors (up to 8 decimal places). Results are displayed with up to 6 decimal places, with trailing zeros removed for readability. For scientific or engineering work, always verify with official standards.
