Convert Miles to Parsecs (mi to pc) ▶ Conversion Table
How to convert1 parsec (pc) = 1.91735E+13 mile (mi). Parsec (pc) is a unit of Length used in Metric system. Mile (mi) is a unit of Length used in Standard system. Parsec: A Unit of LengthA parsec is a unit of length that is often used in astronomy to measure the large distances to astronomical objects outside the Solar System. It is approximately equal to 3.26 light-years or 206,265 astronomical units (au), which are the average distances from the Earth to the Sun. One parsec is about 30.9 trillion kilometres or 19.2 trillion miles. Definition of the parsecThe word parsec is a combination of “parallax” and “arcsecond”, which are terms related to the measurement of angles. Parallax is the apparent shift in position of an object when viewed from different perspectives. Arcsecond is a unit of angle that is equal to one sixtieth of an arcminute, or one three thousand six hundredth of a degree. A parsec is defined as the distance at which one astronomical unit subtends an angle of one arcsecond. In other words, it is the distance from which the Earth-Sun distance would appear as one arcsecond on the sky. This can be illustrated by an imaginary right triangle, where the adjacent side is one au, the opposite side is one parsec, and the angle opposite to the parsec side is one arcsecond. History of the parsecThe concept of the parsec was first proposed by the British astronomer Herbert Hall Turner in 1913, as a convenient unit for expressing stellar distances. He coined the term by blending “parallax” and “second”. He also suggested using the symbol “pc” for parsec. The first measurement of a stellar parallax was made by Friedrich Bessel in 1838, for the star 61 Cygni. He found that the star had a parallax of 0.314 arcseconds, which corresponds to a distance of about 10.4 parsecs. Since then, many more stars have been measured for their parallaxes, using various methods such as telescopes, satellites and interferometers. The parsec is now widely used in astronomy and astrophysics, especially for objects within and around the Milky Way galaxy. For more distant objects, such as galaxies and quasars, larger units such as kiloparsecs (kpc), megaparsecs (Mpc) and gigaparsecs (Gpc) are used. How to convert parsecTo convert parsecs to other units of length, we can use the following conversion factors:
To convert other units of length to parsecs, we can use the inverse of these conversion factors:
Where parsec is usedThe parsec is mainly used in astronomy and astrophysics, as it is a convenient unit for expressing distances between stars and other celestial objects. For example:
The parsec can also be used in other fields that deal with large distances or angles, such as geodesy, navigation and surveying. Example conversions of parsec to other unitsHere are some examples of converting parsecs to other units of length:
To convert one parsec to meters, we multiply by the conversion factor: 1 pc × 3.0857 × 10^16 m/pc = 3.0857 × 10^16 m
To convert 10 parsecs to miles, we multiply by the conversion factor: 10 pc × 1.9174 × 10^13 mi/pc = 1.9174 × 10^14 mi
To convert 0.01 parsecs to astronomical units, we multiply by the conversion factor: 0.01 pc × 2.06265 × 10^5 au/pc = 2.06265 × 10^3 au
To convert 100 parsecs to light-years, we multiply by the conversion factor: 100 pc × 3.26156 ly/pc = 326.156 ly
To convert one meter to parsecs, we divide by the conversion factor: 1 m / (3.0857 × 10^16 m/pc) = 3.24078 × 10^-17 pc
To convert one mile to parsecs, we divide by the conversion factor: 1 mi / (1.9174 × 10^13 mi/pc) = 5.21553 × 10^-14 pc
To convert one astronomical unit to parsecs, we divide by the conversion factor: 1 au / (2.06265 × 10^5 au/pc) = 4.84814 × 10^-6 pc
To convert one light-year to parsecs, we divide by the conversion factor: 1 ly / (3.26156 ly/pc) = 0.306601 pc Mile: A Unit of LengthThe mile is a unit of length that is equal to 5,280 feet or 1,760 yards. It is based on the older English unit of length that was used before the adoption of the metric system. The mile is also a derived unit in the British imperial and US customary systems of measurement. The symbol for mile is mi or m. The mile is most commonly used when expressing distances on land or in air travel. The mile is also used for measuring speed, such as miles per hour (mph). The mile is sometimes distinguished from other types of miles, such as the nautical mile or the geographical mile, by using the term statute mile. In this article, we will explore the definition, history, usage and conversion of the mile as a unit of length. Definition of the MileThe mile is a unit of length that is equal to 5,280 feet or 1,760 yards. It is defined as 1,609.344 meters by international agreement in 1959. One foot is equal to 0.3048 meter and one yard is equal to 0.9144 meter. The definition of the mile has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the mile as based on the meter was agreed upon by an international treaty in 1959. History of the MileThe origin of the mile as a unit of length can be traced back to ancient times, when it was used as a measure of distance based on the human pace. The word mile comes from the Latin word mille, which means thousand. It referred to the distance of one thousand paces, which was about 5,000 Roman feet or 1.48 kilometers. The mile was adopted by other countries that followed the Roman system of measurement, such as England and France. It varied in length from country to country and from time to time, depending on local standards and methods of measurement. The mile was standardized in England by an act of Parliament in 1593, which set it as a distance of 8 furlongs or 5,280 feet. A furlong was a measure of distance used for plowing fields and was equal to 660 feet or 40 rods. A rod was a measure of length used for surveying land and was equal to 16.5 feet or 5.5 yards. The mile was adopted by other countries that followed the English system of measurement, such as the United States and Canada. It was also incorporated into the imperial system of measurement, which was established by an act of Parliament in 1824. The imperial system was based on seven base units that could be derived from natural and traditional units. The mile remained as a derived unit in the imperial system, but it was no longer recommended for use in scientific and technical fields. Usage of the MileThe mile is a unit of length that is used for measuring distances on land or in air travel. For example:
The mile is commonly used in everyday life, especially in countries that follow the British imperial or US customary systems of measurement. Some examples are:
The mile is also used for measuring speed, such as miles per hour (mph). This is a measure of how fast an object moves in relation to another object or point. For example:
Example Conversions of Mile to Other UnitsThe mile can be converted to other units of length by using different factors and formulas. Here are some examples of conversion for different types of units:
1 mi x 5,280 = 5,280 ft
1 mi x 1,760 = 1,760 yd
1 mi x 1,609.344 = 1,609.344 m
1 mi x 1.609344 = 1.609344 km
1 mi / 1.150779 = 0.868976 nmi
1 mi / 0.869 = 1.151 mi
1 ft / 5,280 = 0.000189 mi
1 yd / 1,760 = 0.000568 mi
1 m / 1,609.344 = 0.000621 mi
