About converting Kilometer to Nanometer

Converting Kilometer to Nanometer is a common length conversion. One kilometer (km) equals 1,000,000,000,000 nanometer (nm). Kilometers are used for road distances in most countries outside the United States.

This conversion is commonly needed for travel planning and navigation, construction and home improvement, athletics and sports measurements. Nanometers are used in nanotechnology, semiconductor manufacturing, and wavelength measurements.

To put kilometer in perspective: a 10-minute walk (about 1 km). In nanometer, common references include the width of a DNA double helix (about 2 nm).

Did you know?

The word 'kilometer' comes from the Greek 'khilioi' (thousand) and 'metron' (measure).
