Frequently asked questions
What is the source unit in this conversion?
The source unit is the astronomical unit (AU). An astronomical unit (AU) is the mean Earth-Sun distance, about 149.6 million kilometers.
What is the destination unit in this conversion?
The destination unit is the parsec (pc). A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
How do I convert astronomical unit to parsec?
Multiply the astronomical unit value by 4.84813681e-6. For example, 10 AU × 4.84813681e-6 = 4.84813681e-5 pc.
Is the astronomical unit to parsec 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 astronomical unit needs to be compared with, or reported in, parsec.
Can I convert parsec back to astronomical unit?
Yes. Multiply the parsec value by 206264.8062 to get astronomical unit.

About this conversion
This page converts astronomical unit (AU) to parsec (pc) within the astronomy converter.
An astronomical unit (AU) is the mean Earth-Sun distance, about 149.6 million kilometers.
A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
The formula is parsec = astronomical unit × 4.84813681e-6, 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.
Use the calculator above for instant results, or the table below for common astronomical unit values already converted to parsec.
