How to convert astronomical units to parsecs
1 astronomical unit is equal to 0.000004848136811 parsecs, and 1 parsec is equal to 206,264.8062 astronomical units. To convert, multiply by the conversion factor:
parsecs = astronomical units × 0.000004848136811
parsecs = astronomical units ÷ 206,264.8062Example: convert 15 au to pc: 15 × 0.000004848136811 = 0.00007272205217 pc.
