nanometer to millimeter

Convert nanometer (nm) to millimeter (mm). Use an editable length converter, conversion formula, and reference table.

0.000001

1 nm = 0.000001 mm

Calculated in your browser

Conversion formula

mm = nm × 0.000001

One nanometer equals 0.000001 millimeter. Multiply your value in nanometer by this factor to get millimeter. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 nanometer:
5 × 0.000001 = 0.000005 mm

About these measurements

Length measures the distance between two points.

The base reference used here is the meter. One nanometer is 1e-9 base units; one millimeter is 0.001 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 nm to mm?

Multiply the quantity in nm by 0.000001. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the millimeter to nanometer converter.
