Convert 21 Bohr Radius to Astronomical Unit

21 a₀ (Bohr radius) is equal to 0.000000000000000000007428395990896022 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.

• 21 a₀ × 3.5373314242362E-22 = 7.428395990896E-21 AU
• 21 a₀ ÷ 2.82698984084E+21 = 7.428395990896E-21 AU
