How to use it
- Type the value in the nanometers box.
- Read the result in micrometers as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
µm = nm × 0.001
Multiply the value in nanometers by 0.001 to get micrometers.
Example
To convert 25 nm to micrometers: 25 × 0.001 = 0.025 µm.

About the units
- Nanometer
- A nanometer is one billionth of a meter, used for light wavelengths and chip feature sizes.
- Micrometer
- A micrometer (micron) is one millionth of a meter, used for hair width, filters and coating thickness.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many micrometers are in one nanometer?
1 nm = 0.001 µm exactly.
How do I convert nanometers to micrometers?
Use µm = nm × 0.001. For example, 25 nm = 0.025 µm.
How many nanometers are in one micrometer?
1 µm = 1,000 nm.
Are the inch, foot and mile factors exact or rounded?
They are exact by definition. Since the 1959 agreement one inch is exactly 2.54 cm, one foot 0.3048 m and one mile 1609.344 m.
What is the difference between a mile and a nautical mile?
A statute mile is 1609.344 meters and is used on roads. A nautical mile is 1852 meters and is used at sea and in aviation.
