Parsec (pc). A parsec is about 3.26 light years and is used by astronomers for distances between stars.
Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
There are 3.26156 light years in one parsec.
Multiply the number of parsecs by 3.26156. For example, 10 parsecs equal 32.6156 light years.
One light year equals 0.306601 parsecs.
39.1388 light years. Other common values: 5 parsecs = 16.3078 light years and 100 parsecs = 326.156 light years.
