How to convert nanometers to micrometers
To convert a measurement in nanometers to micrometers, multiply the value by 0.001. The conversion factor comes from the relationship between both units and the meter (the SI base unit of length).
For example, to convert 5 nm to micrometers: 5 × 0.001 = 0.005 µm.
What is a nanometer?
A nanometer is a metric unit of length equal to one billionth of a meter (0.000000001 m) or one thousandth of a micrometer. The nanometer gained prominence in the late 20th century with advances in nanotechnology and semiconductor manufacturing. The prefix 'nano' comes from the Greek 'nanos' (dwarf).
Common uses of nanometers include: Semiconductor transistor sizes (e.g. 5nm, 3nm chips); Light wavelengths (visible light: 380–700 nm); DNA strand diameter (~2.5 nm); UV protection ratings and sunscreen specifications.
What is a micrometer?
A micrometer (micron) is a metric unit of length equal to one millionth of a meter (0.000001 m) or one thousandth of a millimeter. The term 'micron' was officially revoked as an SI unit name in 1967 in favor of 'micrometer', though 'micron' remains common in industry. The unit became critical with the development of microscopy.
Common uses of micrometers include: Semiconductor chip fabrication (process nodes); Bacteria and cell biology measurements; Surface roughness in manufacturing; Fiber optic cable diameter specifications.

Frequently asked questions
How many micrometers are in one nanometer?
One nanometer (nm) equals 0.001 micrometers (µm). Multiply any value in nanometers by 0.001 to convert to micrometers.
How do I convert nanometers to micrometers?
Multiply the value in nanometers by 0.001. For example, 5 nm × 0.001 = 0.005 µm.
How do I convert micrometers to nanometers?
Multiply the value in micrometers by 1,000, or divide by 0.001. Use the swap button on the converter above to reverse the direction.
Is the nanometer to micrometer conversion exact?
Yes, metric-to-metric length conversions are exact because all metric units are defined as powers of 10 relative to the meter.
What is the formula for nanometers to micrometers?
The formula is: µm = nm × 0.001. This is derived from the definition of both units relative to the meter (the SI base unit of length).
