What is a megaparsec?
The megaparsec is used for distances in space, where ordinary units run out of room. One megaparsec equals 3.085678e+22 meters, so every conversion on this page starts from that single number.
Written as an everyday number it looks unwieldy, so astronomers work in scientific notation and in whichever unit keeps the numbers small for the job at hand. Converting megaparsecs into meters or kilometers shows just how much space there is between objects in the sky.
In writing, the megaparsec is usually shortened to "Mpc". One megaparsec is 3.085678e+22 meters, and that ratio is what every figure on this page is built from.
