Nanometers to Kilometers Converter

1 nanometer (nm) equals 1 × 10-12 kilometers (km).

Quick answer

  • 1 nanometer = 1 × 10-12 kilometers
  • 1 kilometer = 1,000,000,000,000 nanometers
  • Formula: km = nm × 1 × 10-12

1 nanometer = 1 × 10-12 kilometers

How to convert nanometers to kilometers

km = nm × 1 × 10-12

To convert nanometers to kilometers, multiply the number of nanometers by 1 × 10-12.

Example: 18 nm to km

  1. Start with the value in nanometers: 18 nm.
  2. Multiply by 1 × 10-12: 18 × 1 × 10-12 = 1.8 × 10-11.
  3. Result: 18 nanometers = 1.8 × 10-11 kilometers.

Going the other way, 1 kilometer = 1,000,000,000,000 nanometers, so to convert kilometers back to nanometers you divide by the same number. See kilometers to nanometers.
