How to convert parsecs to astronomical units
1 parsec is equal to 206,264.8062 astronomical units, and 1 astronomical unit is equal to 0.000004848136811 parsecs. To convert, multiply by the conversion factor:
astronomical units = parsecs × 206,264.8062
astronomical units = parsecs ÷ 0.000004848136811Example: convert 15 pc to au: 15 × 206,264.8062 = 3,093,972.094 au.
