How to Convert Angstrom to Nanometer
- 1 Å = 0.1 nm
- 1 nm = 10 Å
- Example: convert 15 Å to nm: 15 Å = 15 × 0.1 nm = 1.5 nm
Formula
nm = Å ÷ 10
Derivation from SI units:
- 1 Å = 10⁻¹⁰ m = 0.1 nm
- 1 nm = 10⁻⁹ m
- 1 Å = 1 × 10⁻¹⁰ m ÷ 1 × 10⁻⁹ m per nm = 0.1 nm
Both units are defined exactly, so the factor is exact. Angstrom definition: angstrom; Nanometer definition: nanometer.
Worked examples
- A carbon–carbon bond length of 1.54 Å is 0.154 nm.
1.54 Å × 0.1 = 0.154 nm - Green light at 5000 Å is 500 nm.
5000 Å × 0.1 = 500 nm

Where it's used
Crystallography and older spectroscopy data in ångströms are converted to nanometres, the SI-preferred unit. Divide by 10.

Frequently asked questions
How many angstroms are in a nanometer?
Exactly 10.
How many nanometers are in 1 angstrom?
1 Å = 0.1 nm.
How do I convert angstroms to nanometers?
Multiply the value in Å by 0.1, or divide it by 10. For example, 15 Å × 0.1 = 1.5 nm.
Is the Å to nm conversion exact?
Yes. Both units are defined exactly, and 1 Å is exactly 0.1 nm.
