1 millimeter (mm) = 1,000,000 nanometers (nm). To convert, multiply by 1,000,000: nm = mm × 1,000,000. For example, 5 mm = 5,000,000 nm.
nm = mm × 1,000,000

The two units
Millimeter (mm). One thousandth of a meter.
Nanometer (nm). One billionth of a meter, the scale used for light wavelengths and chip features.
Because both units are defined in terms of the same base unit, the factor 1,000,000 is exact, not a rounded measurement.
