1 angstrom (Å) equals 0.1 nanometers (nm).
Table of Contents
An angstrom is a unit of length commonly used to measure atomic scales, while a nanometer is another unit at the nanoscale. Since 1 angstrom is one tenth of a nanometer, converting between them involves multiplying or dividing by 0.1 accordingly.

Conversion Formula
The formula to convert angstroms to nanometers is:
nanometers = angstroms × 0.1
Because 1 angstrom equals 10⁻¹⁰ meters and 1 nanometer equals 10⁻⁹ meters, an angstrom is one tenth of a nanometer. Multiplying the angstrom value by 0.1 converts it to nanometers.
Example:
- Convert 5 angstrom to nm
- nanometers = 5 × 0.1 = 0.5 nm
Conversion Example
- Convert 12 angstrom to nm:
- Multiply 12 by 0.1
- 12 × 0.1 = 1.2 nm
- So, 12 angstrom equals 1.2 nm.
- Convert 0.5 angstrom to nm:
- 0.5 × 0.1 = 0.05 nm
- This shows smaller subatomic distances in nm.
- Convert 20 angstrom to nm:
- 20 × 0.1 = 2 nm
- This is a simple scale up to nanometers.

Conversion Definitions
Angstrom: An angstrom is a unit of length equal to 10⁻¹⁰ meters, used frequently in physics and chemistry for atomic scale measurements. It is named after Anders Jonas Ångström, and commonly applied to express sizes of atoms, molecules, and wavelengths of light.
Nanometer (nm): A nanometer equals 10⁻⁹ meters and measures extremely small distances, such as semiconductor features or molecular sizes. Nanometers are widely used in nanotechnology and optical sciences to represent dimensions at the nanoscale level.
Conversion FAQs
Why is 1 angstrom equal to 0.1 nanometers?
Because an angstrom is defined as 10⁻¹⁰ meters and a nanometer as 10⁻⁹ meters, 1 angstrom is one tenth of a nanometer. This ratio comes from the metric prefixes where nano means 10⁻⁹, and angstrom is a smaller unit used before nanometer became standard in sciences.
Can I use this conversion for measuring wavelengths of light?
Yes, angstroms and nanometers both describe wavelengths of electromagnetic radiation, but nanometers are more common now. Converting between them helps compare data or use measurement units consistent with instruments or scientific literature.
Does converting from angstroms to nanometers lose precision?
Not really; since the conversion involves multiplying by 0.1, the precision depends on decimal places used. Both units describe very small distances, so rounding errors could happen if using too few decimals, but the conversion itself is exact.
Are angstroms still used in modern science?
While nanometers are more popular now, angstroms remain in use in fields like crystallography and atomic physics due to historical convention and convenient scale when describing atomic distances.
How to convert nanometers back to angstroms?
To convert nanometers to angstroms, multiply the nanometer value by 10. This reverses the factor used going from angstroms to nanometers, since 1 nm equals 10 angstroms.
