How to convert atomic units of length to angstroms
1 a.u. of length is equal to 0.5291772109 angstroms, and 1 angstrom is equal to 1.889726125 atomic units of length. To convert, multiply by the conversion factor:
angstroms = atomic units of length × 0.5291772109
angstroms = atomic units of length ÷ 1.889726125Example: convert 15 a₀ to Å: 15 × 0.5291772109 = 7.937658164 Å.

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
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)
