1 μm = 1000 nm
1 Micrometer (μm) = 1000 Nanometer (nm).
If you want to reverse convert, use Nanometer → Micrometer. 1 nm = 0.001 μm. You can also explore the full Length converter page for more cross conversions.
Conversion formula
Micrometer to Nanometer formula: value in nm = value in μm × 1000.
Nanometer to Micrometer formula: value in μm = value in nm × 0.001.
How to convert Micrometer to Nanometer
To convert Micrometer to Nanometer, multiply the value in μm by 1000. This gives the result in nm.
For example, 1 μm = 1000 nm and 10 μm = 10000 nm.
What is Micrometer?
Micrometer (μm): One millionth of a metre, also called a micron. It describes the sizes of cells, fine fibres and thin coatings. 1 μm = 0.001 mm = 10⁻⁶ m.
What is Nanometer?
Nanometer (nm): One billionth of a metre. It is used for light wavelengths, thin films and nanoscale structures, far below ordinary ruler measurements. 1 nm = 0.001 μm = 10⁻⁹ m.
FAQ
How many nanometer are in 1 micrometer?
There are 1000 nm in 1 μm.
Why can conversion results differ slightly?
Check the unit definition and rounding. US and imperial measures can differ; rounding intermediate values can also change the final digits.
How do I convert micrometer to nanometer?
Multiply the value in μm by 1000 to get the value in nm.
