parsecs in English

noun
1
a unit of distance used in astronomy, equal to about 3.26 light years (3.086 × 10 13 kilometers). One parsec corresponds to the distance at which the mean radius of the earth's orbit subtends an angle of one second of arc.
But cosmologists are so comfortable with millions and billions that none of them feel the urge to invent a unit much beyond the light-year or the parsec .
