How to convert petameters to atomic units of length
1 petameter is equal to 1.889726125 × 10²⁵ atomic units of length, and 1 a.u. of length is equal to 5.291772109 × 10⁻²⁶ petameters. To convert, multiply by the conversion factor:
atomic units of length = petameters × 1.889726125 × 10²⁵
atomic units of length = petameters ÷ 5.291772109 × 10⁻²⁶Example: convert 1 Pm to a₀: 1 × 1.889726125 × 10²⁵ = 1.889726125 × 10²⁵ a₀.
