About Rod
The rod (pole or perch) equals 16.5 feet (5.0292 m). Four rods make a chain, and it still appears in older deeds and fencing estimates.
Common uses: historic deeds, fencing, surveying.
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.
