How to convert angstroms to atomic units of length
1 angstrom is equal to 1.889726125 atomic units of length, and 1 a.u. of length is equal to 0.5291772109 angstroms. To convert, multiply by the conversion factor:
atomic units of length = angstroms × 1.889726125
atomic units of length = angstroms ÷ 0.5291772109Example: convert 15 Å to a₀: 15 × 1.889726125 = 28.34589187 a₀.

About the angstrom
The ångström is 10⁻¹⁰ meters (0.1 nm). It's used for atomic radii, chemical bond lengths and crystal lattice spacing.
Symbol: Å · 1 Å = 1 × 10⁻¹⁰ m · Category: Metric (SI)
About the a.u. of length
The atomic unit of length is the Bohr radius, about 5.29 × 10⁻¹¹ m: the most probable distance between the proton and electron in a hydrogen atom.
Symbol: a₀ · 1 a₀ = 5.291772109 × 10⁻¹¹ m · Category: Atomic & physics
