How to convert exameters to atomic units of length
1 exameter is equal to 1.889726125 × 10²⁸ atomic units of length, and 1 a.u. of length is equal to 5.291772109 × 10⁻²⁹ exameters. To convert, multiply by the conversion factor:
atomic units of length = exameters × 1.889726125 × 10²⁸
atomic units of length = exameters ÷ 5.291772109 × 10⁻²⁹Example: convert 1 Em to a₀: 1 × 1.889726125 × 10²⁸ = 1.889726125 × 10²⁸ a₀.
