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 um (um) belongs to the a different measurement system and is typically found in measurements related to various applications. By definition, one nanometer is one billionth of a meter (10⁻⁹ m). The conversion factor between these two units is 0.001: multiplying any value in nm by this number gives the equivalent in um. For example, 10 nm equals 0.0100 um. Going the other direction, 1 um equals 1000 nm.
Frequently asked questions
1 nanometer is equal to exactly 0.001 um (and conversely, 1 um = 1000 nanometer). This factor is fixed by international definition and does not vary.
