How to convert angstroms to astronomical units
1 angstrom is equal to 6.684587122 × 10⁻²² astronomical units, and 1 astronomical unit is equal to 1.495978707 × 10²¹ angstroms. To convert, multiply by the conversion factor:
astronomical units = angstroms × 6.684587122 × 10⁻²²
astronomical units = angstroms ÷ 1.495978707 × 10²¹Example: convert 1 Å to au: 1 × 6.684587122 × 10⁻²² = 6.684587122 × 10⁻²² au.
