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.

| 1,000 km | 1 × 10^15 |
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.
