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