Kilometer to Nanometer

1 km = 1,000,000,000,000 nm

One kilometer equals 1,000,000,000,000 nanometers, and one nanometer equals 1e-12 kilometers.

Kilometer to Nanometer formula

nm = km × 1000000000000

To convert kilometers to nanometers, multiply the value by 1000000000000. One kilometer equals 1,000,000,000,000 nanometers.

Step-by-step examples

Convert 1 kilometers to nanometers

  1. 1Start with the value in kilometers: 1 km.
  2. 2Multiply by the conversion factor 1000000000000.
  3. 31 × 1000000000000 = 1,000,000,000,000 nm.

Result: 1 km = 1,000,000,000,000 nm

Convert 10 kilometers to nanometers

  1. 1Start with the value in kilometers: 10 km.
  2. 2Multiply by the conversion factor 1000000000000.
  3. 310 × 1000000000000 = 10,000,000,000,000 nm.

Result: 10 km = 10,000,000,000,000 nm

Convert 100 kilometers to nanometers

  1. 1Start with the value in kilometers: 100 km.
  2. 2Multiply by the conversion factor 1000000000000.
  3. 3100 × 1000000000000 = 100,000,000,000,000 nm.

Result: 100 km = 100,000,000,000,000 nm
