Convert parsec to chain (US survey)
Enter a value below to convert parsec [pc] to chain (US survey) [ch (US)]. Reverse conversion: Convert chain (US survey) to parsec.
1 pc = 1.5339e+15 ch (US). To convert parsec to chain (US survey), multiply the value by 1.5339e+15; to go the other way, divide by it (1 ch (US) = 6.5194e-16 pc). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Parsec: Definition and Use
A parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years. It is the distance at which one astronomical unit subtends an angle of one arcsecond.
History/Origin
The term "parsec" is a portmanteau of "parallax" and "second," coined by British astronomer Herbert Hall Turner in 1913.
Current Use
The parsec is the preferred unit of distance in astronomy and astrophysics for expressing the distances to stars and galaxies.
Chain (Us Survey): Definition and Use
A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.
History/Origin
The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey chain was used for land surveying in the United States.
