How to convert points to atomic units of length
1 point is equal to 6,666,533.829 atomic units of length, and 1 a.u. of length is equal to 1.500029889 × 10⁻⁷ points. To convert, multiply by the conversion factor:
atomic units of length = points × 6,666,533.829
atomic units of length = points ÷ 1.500029889 × 10⁻⁷Example: convert 1 pt to a₀: 1 × 6,666,533.829 = 6,666,533.829 a₀.
