How to convert parsecs to X-units
1 parsec is equal to 3.079272694 × 10²⁹ X-units, and 1 x-unit is equal to 3.24752011 × 10⁻³⁰ parsecs. To convert, multiply by the conversion factor:
X-units = parsecs × 3.079272694 × 10²⁹
X-units = parsecs ÷ 3.24752011 × 10⁻³⁰Example: convert 1 pc to xu: 1 × 3.079272694 × 10²⁹ = 3.079272694 × 10²⁹ xu.

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.
