Multiply the number of Nanometers by 0.001 to get Micrometers. Formula: μm = nm × 0.001. Example: 10 nm × 0.001 = 0.01 μm. To reverse, divide Micrometers by 0.001 to get Nanometers.

To convert Nanometer to Micrometer, multiply by 0.001. Example: 10 nm = 0.01 μm
To convert Micrometer back to Nanometer, divide by 0.001 (multiply by 1000). Use the swap button above.
Start with 100 Nanometers = 0.1 μm as your reference point. Scale up or down from there.
1 μm = 1,000 nm exactly. Chip manufacturing spans both scales: older "micron" process nodes (1μm, 0.5μm) transitioned to nm nodes (180nm, 90nm, 7nm). Process engineers converting between generations routinely switch between μm and nm specifications.
Confocal microscopes resolve at ~200–500 nm (super-resolution) to ~1 μm (conventional). Biologists comparing imaging modalities convert between nm and μm resolution specifications for every microscope selection and experimental design decision.
Single-mode fibre core diameter is 9 μm (9,000 nm) while wavelength-scale features in photonic crystal fibres are ~1,000 nm (1 μm). Fibre engineers convert between μm and nm throughout photonic fibre design.
Drug nanoparticles for injection are 10–200 nm while inhaled particles must be 1–5 μm for lung deposition. Pharmaceutical engineers convert between nm and μm for every formulation and particle size specification.
MEMS device features use μm while thin film coatings use nm — engineers designing MEMS with surface coatings convert between μm structural features and nm coating thicknesses in every device design.
The nm-to-μm boundary (at 1,000 nm = 1 μm) is one of the most important transitions in materials science — bridging quantum effects (nm) with classical mechanics (μm). Researchers working at this boundary convert between nm and μm constantly.
The Nanometer is a unit of Length measurement (symbol: nm). 1 nm = 0.001 μm. Used in scientific and practical Length measurement applications.
The Micrometer is a unit of Length measurement (symbol: μm). It is part of an internationally recognised measurement system used alongside the Nanometer.
The nanometre owes its name to the Greek 'nanos' (dwarf) combined with 'metre'. The prefix 'nano' was formally adopted by the International Committee for Weights and Measures in 1960 as part of the SI prefix system. Before the nanometre became standard, atomic-scale scientists used angstroms (1 nm = 10 Å), a unit named after Swedish spectroscopist Anders Ångström. The nanometre rose to public prominence in the 1980s and 1990s alongside the emergence of nanotechnology and semiconductor manufacturing, where transistor feature sizes first crossed the nanometre threshold around 1995 with the 180nm process node. Today the nanometre defines the entire semiconductor industry — every chip generation is named by its nm node size.
The micrometre was named in 1879 by the International Committee for Weights and Measures. The micrometer screw gauge was first described by William Gascoigne in the 1630s, though the modern calliper was developed in the 1840s by Jean-Louis Palmer in France.
Common use: Nanometer to Micrometer conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
