Convert parsecs to megaparsecs

Explanation

From this page you can convert parsecs to megaparsecs (or pc to Mpc) simply, by using the application above.

In case you are wondering, to convert from parsecs to megaparsecs you need to multiply by 0.000001. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 pc=0.000001 Mpc

parsecspc

dimension	length
symbol	pc

The parsec (pc) is unit of length used in astronomy.

The unit is used to express distances inside or between galaxies. For example, the Sun is located approximately 8000 parsecs from the center of the Milky Way.

Definition of the parsec

A parsec is defined as the distance at which 1 Astronomical Unit subtends an angle of 1 second of arc.

International Astronomical Union

Value

In this converter, we use the approximate value of 30856775814913673 meters. If you need an exact equivalence (and why wouldn't you), you should know that πpc (pi parsecs) exactly equals 96939420213600000 m.

Some Facts

Let's see if we can get an idea of how big a parsec is.

One of the fastest man-made object is the Voyager 1 space probe. At its current speed of 17000 meters per second, Voyager 1 would take 57500 years to travel just one parsec away from the Sun.

Some Facts

Galaxies are not evenly distributed in space, they form groups. The Milky Way is part of the unimaginatively named Local Group.

This Local Group counts more than 80 galaxies, most dwarf galaxies with the notable exceptions of the Milky Way and the Andromeda Galaxy. The diameter of the Local Group is roughly 3 megaparsecs.
