Frequently asked questions
What is the source unit in this conversion?
The source unit is the kilometer (km). A kilometer is a metric unit of length equal to 1,000 meters.
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 kilometer to parsec?
Multiply the kilometer value by 3.24077929e-14. For example, 10 km × 3.24077929e-14 = 3.24077929e-13 pc.
Is the kilometer 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 kilometer needs to be compared with, or reported in, parsec.
Can I convert parsec back to kilometer?
Yes. Multiply the parsec value by 3.08567758e+13 to get kilometer.

About this conversion
This page converts kilometer (km) to parsec (pc) within the astronomy converter.
A kilometer is a metric unit of length equal to 1,000 meters.
A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
The formula is parsec = kilometer × 3.24077929e-14, 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 kilometer values already converted to parsec.
