Convert angstroms (Å) to nanometers (nm) instantly
nm = Å × 0.1
To convert angstroms to nanometers, multiply the angstrom value by 0.1 (or divide by 10). Ten angstroms equal one nanometer.

An angstrom is a unit of length equal to 10⁻¹⁰ meters, or one ten-billionth of a meter. It is symbolized by Å and named after Swedish physicist Anders Jonas Ångström. The angstrom is particularly useful for expressing atomic-scale dimensions, such as the size of atoms, molecules, and chemical bonds. For example, the typical atomic radius is on the order of 1-2 angstroms, and visible light wavelengths range from about 4,000 to 7,000 angstroms. While not an SI unit, the angstrom remains widely used in chemistry, physics, crystallography, and materials science for its convenience at the atomic scale.
Example calculation: A carbon-carbon bond length is approximately 1.54 angstroms. Multiply 1.54 × 0.1 = 0.154 nanometers.
There are 10 angstroms in one nanometer. Conversely, one angstrom equals 0.1 nanometers. This makes the conversion simple: just move the decimal point one place.
Angstroms are convenient for atomic-scale measurements because typical atomic dimensions are 1-5 angstroms, which are easier to work with than 0.1-0.5 nanometers. Historical convention in chemistry and crystallography also favors angstroms.
Yes, despite not being an SI unit, angstroms remain widely used in chemistry, crystallography, and materials science. Many scientific papers and databases continue to report atomic distances and wavelengths in angstroms.
Most atoms have radii between 1 and 3 angstroms. For example, a hydrogen atom has a radius of about 0.53 angstroms, while a cesium atom (one of the largest) has a radius of about 2.98 angstroms.
5000 angstroms equals 500 nanometers. Calculate this by multiplying 5000 × 0.1 = 500 nm. This wavelength corresponds to green light in the visible spectrum.
One angstrom equals 0.1 nanometers, 100 picometers, or 10⁻¹⁰ meters. It's about one ten-billionth of a meter, roughly the size of a single atom. For comparison, a human hair is about 1 million angstroms (100,000 nm) thick.
