I'm not sure what a "parsac" is, but "parsec" is the shortcut name for "PARallax SECond of arc", the distance away from the Sun where another object would appear to have an angular parallax shift of one arc-second as compared to the distant background stars. It is approximately equal to 3.26 light-years.
