How to convert micrometers to nanometers
One micrometer equals 1,000 nanometers, so multiply the number of micrometers by 1,000.
nm = µm × 1,000
1 µm = 1,000 nm · 1 nm = 0.001 µm
Worked example
To convert 5 micrometers to nanometers: 5 µm × 1,000 = 5,000 nm.
About micrometers (µm)
A micrometer (micron) is one millionth of a metre, used for cells, fibres and machining tolerances.
About nanometers (nm)
A nanometer is one billionth of a metre. It is used for wavelengths of light and the size of molecules and computer chip features.
