Convert 663 Bohr Radius to Astronomical Unit

663 a₀ (Bohr radius) is equal to 0.0000000000000000002345250734268601 AU (astronomical unit). To convert from Bohr radius to astronomical unit, multiply by 0.00000000000000000000035373314242362006 or divide by 2,826,989,840,840,049,000,000.

• 663 a₀ × 3.5373314242362E-22 = 2.3452507342686E-19 AU
• 663 a₀ ÷ 2.82698984084E+21 = 2.3452507342686E-19 AU
