How to convert nanometers to atomic units of length
1 nanometer is equal to 18.89726125 atomic units of length, and 1 a.u. of length is equal to 0.05291772109 nanometers. To convert, multiply by the conversion factor:
atomic units of length = nanometers × 18.89726125
atomic units of length = nanometers ÷ 0.05291772109Example: convert 15 nm to a₀: 15 × 18.89726125 = 283.4589187 a₀.

About the nanometer
A nanometer is one billionth of a meter. It's used for wavelengths of light (visible light is about 380–750 nm), molecules and chip manufacturing processes.
Symbol: nm · 1 nm = 1 × 10⁻⁹ 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.
