How to convert microinches to astronomical units
1 microinch is equal to 1.697885129 × 10⁻¹⁹ astronomical units, and 1 astronomical unit is equal to 5.889679949 × 10¹⁸ microinches. To convert, multiply by the conversion factor:
astronomical units = microinches × 1.697885129 × 10⁻¹⁹
astronomical units = microinches ÷ 5.889679949 × 10¹⁸Example: convert 1 µin to au: 1 × 1.697885129 × 10⁻¹⁹ = 1.697885129 × 10⁻¹⁹ au.
