One parsec is the distance at which one astronomical unit subtends an angle of one arcsecond.

A parsec is equivalent to 3.26 light years,It is not defined to be 3.26 light years and since a light year is the distance light travels in 1 year 9.46e+15  m (9.46 trillion km),

1 parsec equals 9.46 trillion km * 3.26 = 30.8 trillion km.

1 parsec  = 9.46e+15   * 3.26 =  3.08 e+16  m

order of magnitude = 16
