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