Parsec to Light Year Converter
A parsec (pc) is a unit of distance used in astronomy, equivalent to approximately 3.26 light-years (ly). The term “parsec” is derived from “parallax second,” which is a measure of the apparent shift of nearby stars against distant backgrounds as observed from Earth.
The conversion formula is:
1 pc = 3.2615637769 ly
Example: To convert 15 pc to ly:
15 pc = 15 × 3.2615637769 ly = 48.9234566542 ly
