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