- Multiply by the conversion factor: 5 x 6.519411e-16
- The result is: 3.259705e-15 pc
About Chain
Gunter's chain equals 66 feet (20.1168 m) and underpins the US Public Land Survey System: 10 square chains make one acre.
Common uses: land surveying, cadastral records, cricket pitch length.
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.
