Multiply the number of Angstroms by 0.1 to get Nanometers. Formula: nm = Å × 0.1. Example: 10 Å × 0.1 = 1 nm. To reverse, divide Nanometers by 0.1 to get Angstroms.

| 0.01 Å | 0.001 nm |
| 0.1 Å | 0.01 nm |
| 0.5 Å | 0.05 nm |

| 5 Å | 0.5 nm |
| 10 Å | 1 nm |
| 20 Å | 2 nm |

To convert Angstrom to Nanometer, multiply by 0.1. Example: 10 Å = 1 nm
To convert Nanometer back to Angstrom, divide by 0.1 (multiply by 10). Use the swap button above.
Start with 100 Angstroms = 10 nm as your reference point. Scale up or down from there.
Nanotechnology often bridges angstroms and nanometers — molecular bonds are 1–3 Å while nanoparticle diameters are 1–100 nm. Converting between the two is routine in materials science labs worldwide.
Modern chip transistors are 2–5 nm wide (20–50 Å). Engineers switch between angstroms and nanometers constantly when comparing process node specifications across different manufacturers and generations.
Spectroscopists traditionally express light wavelengths in angstroms (visible: 4000–7000 Å), while modern instruments increasingly output in nanometers. Converting between the two is a daily task in photonics labs.
Crystal lattice spacings are classically reported in angstroms, while modern crystallography software increasingly uses nanometers. Converting between them is required when using legacy datasets with new software.
The DNA double helix is 2 nm (20 Å) wide with 0.34 nm (3.4 Å) between base pairs. Biophysicists routinely convert between angstroms and nanometers when comparing atomic-force microscopy data with sequence analysis.
Optical and protective coatings are specified in nanometers for thickness, but deposition rate monitoring uses angstroms per second. Converting between units is standard in physical vapour deposition processes.
The Angstrom is a unit of Length measurement (symbol: Å). 1 Å = 0.1 nm. Used in scientific and practical Length measurement applications.
The Nanometer is a unit of Length measurement (symbol: nm). It is part of an internationally recognised measurement system used alongside the Angstrom.
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 — a scale that made atomic measurements intuitive. Though not an official SI unit, the angstrom became the 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.
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, scientists used angstroms (1 nm = 10 Å) for atomic-scale measurements. The nanometre rose to prominence in the 1980s and 1990s alongside the development of nanotechnology, electron microscopy, and semiconductor chip manufacturing, where feature sizes first reached the nanometre scale around 1995.
Common use: Angstrom to Nanometer conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
