Multiply the number of Nanometers by 10 to get Angstroms. Formula: Å = nm × 10. Example: 10 nm × 10 = 100 Å. To reverse, divide Angstroms by 10 to get Nanometers.

To convert Nanometer to Angstrom, multiply by 10. Example: 10 nm = 100 Å
To convert Angstrom back to Nanometer, divide by 10 (multiply by 0.1). Use the swap button above.
Start with 100 Nanometers = 1000 Å as your reference point. Scale up or down from there.
1 nm = 10 Å exactly. Spectroscopists working with legacy data in angstroms convert to nanometres for modern publications, or vice versa when comparing with historic spectral atlases. The clean 10:1 ratio makes this one of the simplest cross-unit conversions in science.
Crystal lattice spacings are classically reported in angstroms but modern crystallography software increasingly uses nanometres. Crystallographers convert between the two when using legacy datasets with new software or comparing with historical structural databases.
The DNA double helix is 2 nm (20 Å) wide with 3.4 Å (0.34 nm) between base pairs. Biophysicists working with atomic-force microscopy data convert between angstroms and nanometres when comparing structural models with experimental measurements.
Chip generations are named in nanometres (3nm, 5nm, 7nm) while some atomic layer deposition tools still report in angstroms per cycle. Process integration engineers convert between nm and Å for every deposition rate and thickness specification.
Narrow bandpass optical filters are specified in both angstroms (traditional) and nanometres (modern). Filter designers and spectrometer users convert between the two when sourcing components from suppliers using different unit conventions.
1 nm = 10 Å. This clean ratio makes nm-to-angstrom one of the first cross-unit conversions taught in atomic and molecular physics courses — illustrating how scientific unit systems sometimes overlap with different preferred scales.
The Nanometer is a unit of Length measurement (symbol: nm). 1 nm = 10 Å. Used in scientific and practical Length measurement applications.
The Angstrom is a unit of Length measurement (symbol: Å). 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.
Anders Jonas Ångström (1814–1874) was a Swedish physicist who pioneered spectroscopy. In 1868 he published the first detailed map of the solar spectrum, expressing wavelengths in units of 10⁻¹⁰ metres. Though not an official SI unit, the angstrom became standard in crystallography and spectroscopy because atomic bond lengths (1–3 Å) and visible light wavelengths (4,000–7,000 Å) fall naturally within it. The International Bureau of Weights and Measures officially accepted it in 1907.
Common use: Nanometer to Angstrom conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
