How to convert atomic units of length to picometers
1 a.u. of length is equal to 52.91772109 picometers, and 1 picometer is equal to 0.01889726125 atomic units of length. To convert, multiply by the conversion factor:
picometers = atomic units of length × 52.91772109
picometers = atomic units of length ÷ 0.01889726125Example: convert 15 a₀ to pm: 15 × 52.91772109 = 793.7658164 pm.

About the a.u. of length
The atomic unit of length is the Bohr radius, about 5.29 × 10⁻¹¹ m: the most probable distance between the proton and electron in a hydrogen atom.
Symbol: a₀ · 1 a₀ = 5.291772109 × 10⁻¹¹ m · Category: Atomic & physics
About the picometer
A picometer is 10⁻¹² meters. It's used for atomic and ionic radii and bond lengths; a hydrogen atom is about 50 pm across.
Symbol: pm · 1 pm = 1 × 10⁻¹² m · Category: Metric (SI)
