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 kilometer (km). A kilometer is a metric unit of length equal to 1,000 meters.
How do I convert parsec to kilometer?
Multiply the parsec value by 3.08567758e+13. For example, 10 pc × 3.08567758e+13 = 3.08567758e+14 km.
Is the parsec to kilometer 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, kilometer.
Can I convert kilometer back to parsec?
Yes. Multiply the kilometer value by 3.24077929e-14 to get parsec.

About this conversion
This page converts parsec (pc) to kilometer (km) within the astronomy converter.
A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
A kilometer is a metric unit of length equal to 1,000 meters.
The formula is kilometer = parsec × 3.08567758e+13, 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 parsec values already converted to kilometer.
