How to convert chains (US survey) to parsecs
1 chain (us survey) is equal to 6.51942392 × 10⁻¹⁶ parsecs, and 1 parsec is equal to 1.533877858 × 10¹⁵ chains (US survey). To convert, multiply by the conversion factor:
parsecs = chains (US survey) × 6.51942392 × 10⁻¹⁶
parsecs = chains (US survey) ÷ 1.533877858 × 10¹⁵Example: convert 1 ch (US) to pc: 1 × 6.51942392 × 10⁻¹⁶ = 6.51942392 × 10⁻¹⁶ pc.

About the parsec
A parsec is the distance at which one astronomical unit subtends an angle of one arcsecond: about 3.26 light-years (3.086 × 10¹⁶ m). Astronomers use it for distances to stars.
