Millimeters to Nanometers Converter

1 millimeter (mm) equals 1,000,000 nanometers (nm).

Quick answer

  • 1 millimeter = 1,000,000 nanometers
  • 1 nanometer = 0.000001 millimeters
  • Formula: nm = mm × 1,000,000

1 millimeter = 1,000,000 nanometers

How to convert millimeters to nanometers

nm = mm × 1,000,000

To convert millimeters to nanometers, multiply the number of millimeters by 1,000,000.

Example: 18 mm to nm

  1. Start with the value in millimeters: 18 mm.
  2. Multiply by 1,000,000: 18 × 1,000,000 = 18,000,000.
  3. Result: 18 millimeters = 18,000,000 nanometers.

Going the other way, 1 nanometer = 0.000001 millimeters, so to convert nanometers back to millimeters you divide by the same number. See nanometers to millimeters.
