How to convert1 furlong (fur) = 6.51941E15 parsec (pc). Furlong (fur) is a unit of Length used in Standard system. Parsec (pc) is a unit of Length used in Metric system. Furlong: A Unit of Length Used in the US Customary SystemThe furlong (fur) is a unit of length in the US customary system, which is one of the systems of measurement used in the United States and some other countries. The furlong is equal to 220 yards, which is an eighth of a mile. The furlong is also a derived unit in the imperial system, which is the official system of measurement for the United Kingdom and some other Commonwealth countries. The symbol for furlong is fur. The furlong is used for measuring long distances and areas, such as the length of a horse race or the area of a farm. The furlong is named after the furrowlong, which was the length of a furrow in one acre of a plowed open field in medieval England. In this article, we will explore the definition, history, usage and conversion of the furlong as a unit of length. Definition of the UnitThe furlong is a unit of length that is equal to 220 yards. It is defined as 1/8 miles. The mile is defined as 5,280 feet or 1,760 yards. The definition of the furlong has not changed since its origin in medieval England, as part of the old English system of measurement that was based on natural and traditional units. However, the definition of the mile has changed several times 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 feet and yards was agreed upon by an international treaty in 1959. History of the UnitThe origin of the furlong as a unit of length can be traced back to medieval England, when it was used as a measure of land area and distance. The word furlong comes from the Old English words furh (furrow) and lang (long), meaning furrowlong. It referred to the length of a furrow in one acre of a plowed open field, which was a common system of land division and cultivation at that time. The open field was divided into strips or selions, each strip being one furlong long and one rod wide. A rod was equal to 5.5 yards or 16.5 feet. An acre was equal to four rods by 40 rods, or 160 square rods. The furlong was also used as a measure of distance for horse racing and other sports. The standard length of a horse race was four furlongs, or half a mile. This was later increased to eight furlongs, or one mile, which became known as the classic distance for horse racing. The furlong 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, 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 furlong 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 UnitThe furlong is a unit of length that is used for measuring long distances and areas, such as the length of a horse race or the area of a farm. The furlong is commonly used in horse racing, especially in North America and some other countries that follow the US customary system. Some examples are:
The furlong is also used in agriculture, especially in rural areas where farms are still measured by acres and furlongs. Some examples are:
How to ConvertThe furlong can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert furlongs to other units of length in the US customary system, the SI system and other systems:
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 lightyears 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 EarthSun 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 lightyears, 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 lightyear to parsecs, we divide by the conversion factor: 1 ly / (3.26156 ly/pc) = 0.306601 pc Español Russian Français
