About Parsec
The parsec is the distance at which one astronomical unit subtends an angle of one arcsecond, about 3.26 light years. Professional astronomers prefer it to the light year.
Common uses: astrophysics, star catalogues, cosmology.
About Mil/Thou
A mil (or thou) is one thousandth of an inch, 25.4 micrometres. US manufacturing uses it for sheet, film and coating thickness.
Common uses: plastic film, PCB traces, coating thickness.
