How to convert atomic units of length to parsecs
1 a.u. of length is equal to 1.714946546 × 10⁻²⁷ parsecs, and 1 parsec is equal to 5.831085538 × 10²⁶ atomic units of length. To convert, multiply by the conversion factor:
parsecs = atomic units of length × 1.714946546 × 10⁻²⁷
parsecs = atomic units of length ÷ 5.831085538 × 10²⁶Example: convert 1 a₀ to pc: 1 × 1.714946546 × 10⁻²⁷ = 1.714946546 × 10⁻²⁷ 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.
