How to Convert Parsecs to Astronomical Units
To convert from parsecs (pc) to astronomical units (AU), you multiply the distance in parsecs by 206,265. For more information about parsecs as a unit of measurement, visit our parsecs page.
Formula
Astronomical Units = Parsecs × 206,265
or
AU = pc × 206,265
Examples
- 0.000001 pc = 0.000001 × 206,265 = 0.206265 AU
- 0.00001 pc = 0.00001 × 206,265 = 2.06265 AU
- 0.0001 pc = 0.0001 × 206,265 = 20.6265 AU
- 0.001 pc = 0.001 × 206,265 = 206.265 AU
When to Convert Parsecs to Astronomical Units
This conversion is useful when discussing distances in the vastness of space, especially for interstellar distances.
Astronomy
Astronomers use parsecs to measure distances to stars and galaxies, as astronomical units become too small for such vast scales.
Cosmology
In cosmology, parsecs are a fundamental unit for understanding the scale of the universe and the distances to distant celestial objects.

Frequently Asked Questions
What is a parsec (pc)?
A parsec is a unit of length used to measure large distances to astronomical objects outside the Solar System. One parsec is approximately 3.26 light-years or 206,265 astronomical units.
What is an astronomical unit (AU)?
An astronomical unit (AU) is a unit of length, roughly the distance from Earth to the Sun. It is defined as 149,597,870,700 meters.
How do I convert astronomical units to parsecs?
To convert from astronomical units to parsecs, you divide the distance in astronomical units by 206,265. For example, 100 AU is equal to 100 / 206,265 = 0.0004848 pc.
