Ångström to Nanometers Converter

Both Ångström (Å) and Nanometer (nm) are non-SI and SI metrics used in crystallography, atomic physics, semiconductor manufacturing, and molecular biology.

To use the Ångström to Nanometers Converter, enter your Value to Convert, Conversion Direction. The calculator instantly computes Converted Value, Equivalent in Meters (m) and more. Results update in real time as you change any input — no submit button needed.

How to Use This Calculator

Enter your Value to Convert (e.g. 10) and Conversion Direction — choose from Ångström (Å) to Nanometers (nm), Nanometers (nm) to Ångström (Å). Results update instantly as you type — adjust any value to compare scenarios.

The Formula

1 Ångström (Å) = 0.1 Nanometers (nm) = 10⁻¹⁰ meters

1 Nanometer (nm) = 10 Ångströms (Å) = 10⁻⁹ meters

Worked Example

Convert 50 Ångströms (Å) to nanometers (nm):

50 Å × 0.1 = 5.0 nm.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
