How to convert astronomical units to microns
1 astronomical unit is equal to 1.495978707 × 10¹⁷ microns, and 1 micron is equal to 6.684587122 × 10⁻¹⁸ astronomical units. To convert, multiply by the conversion factor:
microns = astronomical units × 1.495978707 × 10¹⁷
microns = astronomical units ÷ 6.684587122 × 10⁻¹⁸Example: convert 1 au to µ: 1 × 1.495978707 × 10¹⁷ = 1.495978707 × 10¹⁷ µ.
