Nanometers to kilometers

1 nanometer in kilometers
1 nm = 1 × 10^-12 km
km = nm × 1 × 10^-12

To convert nanometers to kilometers, multiply by 1 × 10^-12. 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 km = nm × 1 × 10^-12. Both units measure length, so the conversion is a fixed factor that never changes.

Common questions

How many kilometers are in one nanometer?
One nanometer equals 1 × 10^-12 kilometers. km = nm × 1 × 10^-12.
How do you convert nanometers to kilometers?
Use km = nm × 1 × 10^-12. So 10 nm is 1 × 10^-11 km.
How many nanometers are in one kilometer?
One kilometer equals 1,000,000,000,000 nanometers, which is the reverse of the conversion above.
