What is an angstrom used for?

An angstrom is a unit of length used for atomic and molecular scale distances, commonly in crystallography, atomic physics, and describing bond lengths.

Why convert angstroms to astronomical units?

This conversion helps relate atomic-scale measurements to distances on a solar system scale, aiding scientific understanding across vastly different magnitudes.

What does one astronomical unit represent?

One astronomical unit is the defined length of approximately 149,597,870,700 metres, historically representing the average Earth-Sun distance.

What Is This Tool?

This converter enables users to transform length values measured in angstroms, a unit used for atomic and molecular scales, into astronomical units, which represent distances within the Solar System. It helps bridge the gap between extremely small and very large length scales.

How to Use This Tool?

Enter the value in angstroms you wish to convert
Select the input unit as angstrom [A] and the output unit as astronomical unit [AU, UA]
Click the convert button to view the equivalent length in astronomical units
Interpret results, which are usually presented in scientific notation due to scale differences

Key Features

Converts length values from angstroms [A] to astronomical units [AU, UA]
Supports scientific notation for handling extremely small conversion results
Useful for disciplines ranging from crystallography to planetary science
Browser-based and easy to use without specialized software

Examples

1 Å equals approximately 6.6845871226706 × 10⁻²² AU
10 Å equals approximately 6.6845871226706 × 10⁻²¹ AU

Common Use Cases
