How to convert atomic units of length to microns
1 a.u. of length is equal to 0.00005291772109 microns, and 1 micron is equal to 18,897.26125 atomic units of length. To convert, multiply by the conversion factor:
microns = atomic units of length × 0.00005291772109
microns = atomic units of length ÷ 18,897.26125Example: convert 15 a₀ to µ: 15 × 0.00005291772109 = 0.0007937658164 µ.

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 micron
The micron is the older name for the micrometer (one millionth of a meter). It's still common in filtration, semiconductor manufacturing and particle sizes.
