micrometer to nanometer
Convert micrometer (μm) to nanometer (nm). Use an editable length converter, conversion formula, and reference table.
1 μm = 1,000 nm
Conversion formula
One micrometer equals 1,000 nanometer. Multiply your value in micrometer by this factor to get nanometer. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 micrometer:5 × 1,000 = 5,000 nm

About these measurements
Length measures the distance between two points.
The base reference used here is the meter. One micrometer is 0.000001 base units; one nanometer is 1e-9 base units.
Important distinctions
International feet and inches are used. Survey feet are not included.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert μm to nm?
Multiply the quantity in μm by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the nanometer to micrometer converter.
