How to convert gigameters to atomic units of length
1 gigameter is equal to 1.889726125 × 10¹⁹ atomic units of length, and 1 a.u. of length is equal to 5.291772109 × 10⁻²⁰ gigameters. To convert, multiply by the conversion factor:
atomic units of length = gigameters × 1.889726125 × 10¹⁹
atomic units of length = gigameters ÷ 5.291772109 × 10⁻²⁰Example: convert 1 Gm to a₀: 1 × 1.889726125 × 10¹⁹ = 1.889726125 × 10¹⁹ a₀.
