How to convert picometers to atomic units of length
1 picometer is equal to 0.01889726125 atomic units of length, and 1 a.u. of length is equal to 52.91772109 picometers. To convert, multiply by the conversion factor:
atomic units of length = picometers × 0.01889726125
atomic units of length = picometers ÷ 52.91772109Example: convert 15 pm to a₀: 15 × 0.01889726125 = 0.2834589187 a₀.

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)
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
