Angstrom To Nm Conversion Calculator

The Angstrom to Nanometre Converter changes a length between ångströms (Å) and nanometres (nm). Since 1 Å equals exactly 0.1 nm, it multiplies or divides by 10 depending on the direction you choose. The formula used is: nm = Å ÷ 10; Å = nm × 10.

Formula

nm = Å ÷ 10; Å = nm × 10
  • The Angstrom to Nanometre Converter updates instantly as you change the value or direction.
  • Formula: nm = Å ÷ 10; Å = nm × 10
  • Input definitions: • Value: the length to convert • Convert: the direction (Å → nm or nm → Å)
  • One ångström is 10⁻¹⁰ m and one nanometre is 10⁻⁹ m, so 1 Å = 0.1 nm exactly.
  • Ångströms are common in atomic and crystallographic measurements; nanometres are common in nanotechnology and optics.
  • Practical tip: a typical atomic bond length of about 1.5 Å equals 0.15 nm.

Example Calculation

Inputs
  • Value: 10
  • Convert: toNm

10 Å ÷ 10 = 1 nm. Switch the direction to convert nm back to ångströms by multiplying by 10.

Frequently asked questions

How many nanometres are in an ångström?
One ångström equals 0.1 nanometre, because 1 Å = 10⁻¹⁰ m and 1 nm = 10⁻⁹ m.
How do I convert ångströms to nanometres?
Divide the number of ångströms by 10. To go the other way, multiply nanometres by 10.
When is the ångström used?
The ångström is widely used for atomic radii, bond lengths, and X-ray wavelengths, where nanometres would give awkward small decimals.
How accurate is the conversion?
It is exact: the relationship 1 Å = 0.1 nm is a fixed definition, so only display rounding applies.
What is the symbol for the ångström?
It is written Å (an A with a small ring above it), named after the physicist Anders Jonas Ångström.
