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