How to convert atomic units of length to nanometers
1 a.u. of length is equal to 0.05291772109 nanometers, and 1 nanometer is equal to 18.89726125 atomic units of length. To convert, multiply by the conversion factor:
nanometers = atomic units of length × 0.05291772109
nanometers = atomic units of length ÷ 18.89726125Example: convert 15 a₀ to nm: 15 × 0.05291772109 = 0.7937658164 nm.
