Convert parsecs to miles

Explanation

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

In case you are wondering, to convert from parsecs to miles you need to multiply by 1.9174 × 10¹³. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 pc≈1.9174 × 10¹³ mi

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.

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.

The International Mass and Length Units

The International Mass and Length Units are units based on the international yard and the international pound.

They were created in 1959 when Australia, Canada, New Zealand, South Africa, the United Kingdom and the United States of America agreed upon a common definition of the yard and the pound.
