How to convert microns to atomic units of length
1 micron is equal to 18,897.26125 atomic units of length, and 1 a.u. of length is equal to 0.00005291772109 microns. To convert, multiply by the conversion factor:
atomic units of length = microns × 18,897.26125
atomic units of length = microns ÷ 0.00005291772109Example: convert 15 µ to a₀: 15 × 18,897.26125 = 283,458.9187 a₀.

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.
Symbol: µ · 1 µ = 0.000001 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.
