To convert angstroms to astronomical units, multiply the value by 6.68459 × 10⁻²². To go the other way, multiply astronomical units by 1.49598 × 10²¹ to get angstroms.

↔ Convert astronomical units to angstroms instead

🧮 Formula

Angstroms to Astronomical Units
AU = Å × 6.68459 × 10⁻²²
Astronomical Units to Angstroms
Å = AU × 1.49598 × 10²¹

Where

  • Å = the length in angstroms
  • AU = the length in astronomical units
Every unit here is defined by its length in meters, so the conversion factor is (meters per angstrom) ÷ (meters per astronomical unit).
