How to Convert Parsec to Petameter
To convert pc to light-years: multiply by 3.2616. To convert pc to AU: multiply by 206,265.
1 pc = 3.0857 × 10¹⁶ m = 3.2616 ly = 206,265 AU ≈ 30.857 trillion km.
For example, 1 Parsec (pc) = 30.857 Petameter (Pm).

About Parsec (pc)
The parsec is an astronomical unit of length defined as the distance at which one astronomical unit subtends an angle of one arcsecond.
1 pc = 3.0857 × 10¹⁶ m = 3.2616 ly = 206,265 AU ≈ 30.857 trillion km.
To convert pc to light-years: multiply by 3.2616. To convert pc to AU: multiply by 206,265.
Stellar catalogs, galaxy surveys, and cosmological distance calculations.
No known star is within 1 parsec of the Sun. Proxima Centauri is 1.30 pc away, making it the nearest star.
Pronouncing or interpreting 'parsec' as a unit of time (famously misused in Star Wars). It is strictly a distance unit.
The parsec is defined geometrically: if a star's parallax (apparent shift over 6 months) is 1 arcsecond, it's 1 pc away.
