How to convert atomic units of length to microinches
1 a.u. of length is equal to 0.002083374846 microinches, and 1 microinch is equal to 479.9904357 atomic units of length. To convert, multiply by the conversion factor:
microinches = atomic units of length × 0.002083374846
microinches = atomic units of length ÷ 479.9904357Example: convert 15 a₀ to µin: 15 × 0.002083374846 = 0.03125062269 µin.

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 microinch
A microinch is one millionth of an inch (25.4 nm). It's used to specify surface roughness in machining.
