10 km = 10,000,000,000,000 nm. Change the amount below, or read the formula and the reference table further down.

10 kilometers equals

10,000,000,000,000nanometers

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

The formula

Kilometers and nanometers both measure length from the same zero, so a single multiplier does the job.

nm = km × 1,000,000,000,000
