Frequently asked questions
What is the source unit in this conversion?
The source unit is the parsec (pc). A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
What is the destination unit in this conversion?
The destination unit is the astronomical unit (AU). An astronomical unit (AU) is the mean Earth-Sun distance, about 149.6 million kilometers.
How do I convert parsec to astronomical unit?
Multiply the parsec value by 206264.8062. For example, 10 pc × 206264.8062 = 2.06264806e+6 AU.
Is the parsec to astronomical unit conversion exact?
Yes. Both units have a fixed, defined relationship to the astronomy converter's distance base unit, so the conversion factor is exact rather than a measured approximation.
Where is this conversion commonly used?
It's used in astronomy, physics, and space science whenever a distance value expressed in parsec needs to be compared with, or reported in, astronomical unit.
Can I convert astronomical unit back to parsec?
Yes. Multiply the astronomical unit value by 4.84813681e-6 to get parsec.

About this conversion
This page converts parsec (pc) to astronomical unit (AU) within the astronomy converter.
A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
An astronomical unit (AU) is the mean Earth-Sun distance, about 149.6 million kilometers.
The formula is astronomical unit = parsec × 206264.8062, based on each unit's fixed relationship to the astronomy converter's distance base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
