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