How to use it

  1. Type the value in the angstroms box.
  2. Read the result in nanometers as you type, and pick the precision you need.
  3. Swap the direction to convert back, or copy the result.

How it is calculated

nm = Å × 0.1

Multiply the value in angstroms by 0.1 to get nanometers.

Example

To convert 25 Å to nanometers: 25 × 0.1 = 2.5 nm.

About the units

Angstrom
An angstrom is exactly 10^-10 meter, one tenth of a nanometer, used for atomic sizes and bond lengths.
Nanometer
A nanometer is one billionth of a meter, used for light wavelengths and chip feature sizes.

Limits and caveats

  • Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
  • Both unit factors are exact by their official definitions.

Questions about this tool

How many nanometers are in one angstrom?

1 Å = 0.1 nm exactly.

How do I convert angstroms to nanometers?

Use nm = Å × 0.1. For example, 25 Å = 2.5 nm.

How many angstroms are in one nanometer?

1 nm = 10 Å.

Are the inch, foot and mile factors exact or rounded?

They are exact by definition. Since the 1959 agreement one inch is exactly 2.54 cm, one foot 0.3048 m and one mile 1609.344 m.

What is the difference between a mile and a nautical mile?

A statute mile is 1609.344 meters and is used on roads. A nautical mile is 1852 meters and is used at sea and in aviation.
