Convert Millimeters to nanometers
1 millimeter = 1,000,000 nanometers · nm = mm × 1,000,000
When you need this conversion
This conversion goes from millimeters, the metric unit used for hardware, engineering drawings, and anything needing sub-centimeter precision, to nanometers, the scale of semiconductors and light wavelengths. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.

The formula
nm = mm × 1,000,000Because both units measure length, the conversion is a single multiplication by a fixed factor. That factor never changes, so the result is exact.
