Kilometers to nanometers

1 kilometer in nanometers
1 km = 1,000,000,000,000 nm
nm = km × 1,000,000,000,000

To convert kilometers to nanometers, multiply by 1,000,000,000,000. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is nm = km × 1,000,000,000,000. Both units measure length, so the conversion is a fixed factor that never changes.

Common questions

How many nanometers are in one kilometer?
One kilometer equals 1,000,000,000,000 nanometers. nm = km × 1,000,000,000,000.
How do you convert kilometers to nanometers?
Use nm = km × 1,000,000,000,000. So 10 km is 10,000,000,000,000 nm.
How many kilometers are in one nanometer?
One nanometer equals 1 × 10^-12 kilometers, which is the reverse of the conversion above.
