The conversion of 1 parsec to miles equals approximately 19,173,000 miles.
Table of Contents
A parsec is a unit used in astronomy to measure vast distances between stars and galaxies. When converted to miles, it reveals just how immense these cosmic measurements are, with 1 parsec being roughly equivalent to over 19 million miles, showing the scale of the universe.
Conversion Result and Explanation
1 parsec equals about 19,173,000 miles. This conversion helps translate astronomical units into familiar miles, making it easier to grasp the scale of interstellar distances. The calculation uses the standard value of a parsec in meters, then converts meters to miles for practical understanding.

Conversion Formula
The formula to convert parsecs to miles is: miles = parsecs * 19,173,000. This works because a parsec is defined as approximately 3.086 x 10^16 meters, and since 1 mile equals about 1609.34 meters, dividing the meters per parsec by meters per mile gives roughly 19 million miles per parsec. For example, 1 parsec multiplied by 19,173,000 equals about 19,173,000 miles.
Conversion Example
- Convert 2 parsecs:
- Calculate: 2 * 19,173,000 = 38,346,000 miles.
- This shows 2 parsecs equal about 38.346 million miles.
- Convert 0.5 parsecs:
- Calculate: 0.5 * 19,173,000 = 9,586,500 miles.
- This means half a parsec is roughly 9.586 million miles.
- Convert 10 parsecs:
- Calculate: 10 * 19,173,000 = 191,730,000 miles.
- Ten parsecs are about 191.73 million miles in length.
- Convert 3.5 parsecs:
- Calculate: 3.5 * 19,173,000 = 67,105,500 miles.
- Three and a half parsecs equal around 67.1 million miles.

Conversion Definitions
Parsec
A parsec is a unit of distance used in astronomy, equal to approximately 3.086 x 10^16 meters or about 19.173 million miles, measuring the space between stars and galaxies based on the parallax method of triangulation.
Miles
Miles are units of length used mainly in the United States and the UK, where one mile equals about 1,609.34 meters, commonly used for measuring distances in road travel, but also for various other distance measurements.
Conversion FAQs
How accurate is the mile equivalent of a parsec?
The mile value of roughly 19.173 million miles per parsec is based on the accepted astronomical definition of a parsec and standard mile conversions. Slight variations can occur depending on rounding and measurement standards used.
Why is the parsec considered a useful unit in astronomy?
Because it relates to the method of measuring stellar distances using parallax, a parsec provides a practical way to express vast distances in space, making it easier to understand and compare cosmic scales without dealing with extremely large numbers.
Can I use this conversion for intergalactic distances?
While parsecs are suitable for measuring distances within our galaxy and nearby galaxies, for extremely large intergalactic spans, astronomers sometimes prefer light-years or megaparsecs for more convenient figures.
