Astronomers measure cosmic distances in parsecs while popular science tends to use light years, so converting between them is a constant need. One parsec is the distance at which one astronomical unit spans one arcsecond of angle, and it equals about three point two six light years. This converter turns any value in parsecs, light years, astronomical units or kilometers into all of the others at once, so you can move freely between the units scientists and enthusiasts use. It handles the huge numbers involved with scientific notation where needed. Type a value in any field and the rest update as you go. All conversion happens locally in your browser with nothing sent anywhere.
