How to convert kilometers to nanometers
1 kilometer is equal to 1,000,000,000,000 nanometers, and 1 nanometer is equal to 1 × 10⁻¹² kilometers. To convert, multiply by the conversion factor:
nanometers = kilometers × 1,000,000,000,000
nanometers = kilometers ÷ 1 × 10⁻¹²Example: convert 1 km to nm: 1 × 1,000,000,000,000 = 1,000,000,000,000 nm.

About the kilometer
A kilometer is 1,000 meters. It's the standard unit for distances between places, road signs and running races in most countries.
Symbol: km · 1 km = 1,000 m · Category: Metric (SI)
About the nanometer
A nanometer is one billionth of a meter. It's used for wavelengths of light (visible light is about 380–750 nm), molecules and chip manufacturing processes.
Symbol: nm · 1 nm = 1 × 10⁻⁹ m · Category: Metric (SI)
