From theCambridge English Corpus
The distance d to the star is in parsecs (pc).

Answer: a simple factor of 3.26, but astronomers insist on using parsecs for their distance unit, seriously impeding communication with non-astronomers.
From theCambridge English Corpus
Many blazars have apparent superluminal features within the first few parsecs of their jets, probably due to relativistic shock fronts.
