The micrometer (micron)
The micrometer (µm), also called the micron, equals one-millionth of a meter. It is the working unit for semiconductor feature sizes, human hair and cell diameters, and precision-manufacturing tolerances.
Micrometers to Nanometers Converter
1 µm = 1000 nm (micrometer (micron) → nanometer)
1 µm = 1000 nm
1 micrometer (micron) equals 1000 nanometers. To convert micrometers to nanometers, multiply the micrometer (micron) value by 1000. For quick reference: 1 µm = 1000 nm, 5 µm = 5000 nm, 10 µm = 10000 nm, 100 µm = 100000 nm.
Formula
Nanometers = Micrometers × 1000Quick

Real-world reference
A human hair is about 70 µm in diameter. A red blood cell is roughly 7–8 µm across. In nanometers, that gives you: 1 µm = 1000 nm, 10 µm = 10000 nm, 100 µm = 100000 nm.
