1 parsec = 3.259 light-years = 206,265 AU = 30.83 trillion km = 19.16 trillion miles.
The parsec is generally used by astronomers in preference to the light-year. For larger distances, the kiloparsec (kpc) = 1,000 pc or megaparsec (Mpc) = 1,000,000 pc are used.
It is a popular misconception that light-year and parsec are units of time. For example, in the Star Wars movie Episode IV: A New Hope, Han Solo says to Obi-Wan: "You've never heard of the Millennium Falcon?... It's the ship that made the Kessel Run in less than twelve parsecs."
