How to convert micrometers to nanometers
To convert a measurement in micrometers to nanometers, multiply the value by 1,000. The conversion factor comes from the relationship between both units and the meter (the SI base unit of length).
For example, to convert 5 µm to nanometers: 5 × 1,000 = 5,000 nm.
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.
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.
Micrometers to nanometers worked examples
Here are some common values converted:
1 µm = 1,000 nm 5 µm = 5,000 nm 10 µm = 10,000 nm 50 µm = 50,000 nm 100 µm = 100,000 nm
Frequently asked questions
How many nanometers are in one micrometer?
One micrometer (µm) equals 1,000 nanometers (nm). Multiply any value in micrometers by 1,000 to convert to nanometers.
How do I convert micrometers to nanometers?
Multiply the value in micrometers by 1,000. For example, 5 µm × 1,000 = 5,000 nm.
How do I convert nanometers to micrometers?
Multiply the value in nanometers by 0.001, or divide by 1,000. Use the swap button on the converter above to reverse the direction.
Is the micrometer to nanometer 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 micrometers to nanometers?
The formula is: nm = µm × 1,000. This is derived from the definition of both units relative to the meter (the SI base unit of length).
