Convert Astronomical Unit to Angstrom
Input the number of astronomical units you want to convert to angstroms.
How to Convert Astronomical Units to Angstroms
The astronomical unit and angstrom are both units of length. By definition, 1 astronomical unit equals exactly 1.496e21 angstroms. This means to convert astronomical units to angstroms, you multiply by 1.496e21.
Formula
Step-by-Step Example
Convert 5 AU to angstroms:
We need to convert astronomical units to angstroms
Since 1 AU = 1.496e21 Å, multiply by 1.496e21
5 × 1.496e21 = 7.48e21
5 AU = 7.48e21 Å

About These Units
Astronomical Unit (AU)
An astronomical unit (AU) is the average distance from Earth to the Sun: approximately 149.6 million kilometers or 93 million miles. AUs measure distances within our solar system. Mars is 1.52 AU from the Sun, Jupiter is 5.2 AU.
Angstrom (Å)
An angstrom (Å) is a unit equal to 10⁻¹⁰ meters or 0.1 nanometers. Angstroms measure atomic and molecular dimensions, crystal structures, and electromagnetic wavelengths. A hydrogen atom is about 1.2 Å in diameter. Named after physicist Anders Jonas Ångström.
