Nanometers to Astronomical units Converter

1 nanometer (nm) equals 6.6845871 × 10-21 astronomical units (au).

1 nanometer = 6.6845871 × 10-21 astronomical units

How to convert nanometers to astronomical units

au = nm ÷ 1.4959787 × 1020

To convert nanometers to astronomical units, divide the number of nanometers by 1.4959787 × 1020.

Example: 10 nm to au

  1. Start with the value in nanometers: 10 nm.
  2. Divide by 1.4959787 × 1020: 10 ÷ 1.4959787 × 1020 = 6.6845871 × 10-20.
  3. Result: 10 nanometers = 6.6845871 × 10-20 astronomical units.

Going the other way, 1 astronomical unit = 1.4959787 × 1020 nanometers, so to convert astronomical units back to nanometers you multiply by the same number. See astronomical units to nanometers.
