Nanometer to Kilometer Converter

About this conversion

The nanometer (nm) is a unit of length in the metric (SI), commonly used for visible light wavelengths (400–700 nm) and chip transistor node sizes. The kilometer (km) belongs to the metric (SI) and is typically found in measurements related to road and highway distances and geographic measurements. By definition, one nanometer is one billionth of a meter (10⁻⁹ m). One kilometer is one thousand meters. The conversion factor between these two units is 1e-12: multiplying any value in nm by this number gives the equivalent in km. For example, 10 nm equals 0.0000 km. Going the other direction, 1 km equals 1000000000000 nm. Adopted alongside the metric system, the kilometer became the standard unit for land distance in most countries by the 20th century.
