How to convert astronomical units to atomic units of length
1 astronomical unit is equal to 2.826990045 × 10²¹ atomic units of length, and 1 a.u. of length is equal to 3.537331169 × 10⁻²² astronomical units. To convert, multiply by the conversion factor:
atomic units of length = astronomical units × 2.826990045 × 10²¹
atomic units of length = astronomical units ÷ 3.537331169 × 10⁻²²Example: convert 1 au to a₀: 1 × 2.826990045 × 10²¹ = 2.826990045 × 10²¹ a₀.
