⚡ Astronomical Units to Angstroms: the quick answer

1 AU = 1.49598 × 10²¹ Å 1 astronomical unit equals 1.49598 × 10²¹ angstroms

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

↔ Convert angstroms to astronomical units instead

🧮 Formula

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

Where

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