How to convert nanometers to astronomical units
1 nanometer is equal to 6.684587122 × 10⁻²¹ astronomical units, and 1 astronomical unit is equal to 1.495978707 × 10²⁰ nanometers. To convert, multiply by the conversion factor:
astronomical units = nanometers × 6.684587122 × 10⁻²¹
astronomical units = nanometers ÷ 1.495978707 × 10²⁰Example: convert 1 nm to au: 1 × 6.684587122 × 10⁻²¹ = 6.684587122 × 10⁻²¹ au.
