How to convert microinches to atomic units of length
1 microinch is equal to 479.9904357 atomic units of length, and 1 a.u. of length is equal to 0.002083374846 microinches. To convert, multiply by the conversion factor:
atomic units of length = microinches × 479.9904357
atomic units of length = microinches ÷ 0.002083374846Example: convert 15 µin to a₀: 15 × 479.9904357 = 7,199.856535 a₀.

About the microinch
A microinch is one millionth of an inch (25.4 nm). It's used to specify surface roughness in machining.
Symbol: µin · 1 µin = 2.54 × 10⁻⁸ m · Category: Imperial & US customary
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.
