How to convert1 parsec (pc) = 1.01236E+17 foot (ft). Parsec (pc) is a unit of Length used in Metric system. Foot (ft) 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 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 Foot: A Unit of Length Used in the US Customary SystemThe foot (ft) is a unit of length used in the US customary system, which is one of the systems of measurement used in the United States and some other countries. The foot is equal to 12 inches or 0.3048 meter. The foot 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 foot is ft or ′. The foot is used for measuring short distances and dimensions, such as the height of a person or the width of a door. The foot is named after the human foot, which was used as a standard of measurement in ancient times. In this article, we will explore the definition, history, usage and conversion of the foot as a unit of length. Definition of FootThe foot is a unit of length that is equal to 12 inches. It is defined as 0.3048 meter by international agreement in 1959. One inch is equal to 25.4 millimeters. The definition of the foot has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the foot as based on the meter was agreed upon by an international treaty in 1959. History of FootThe origin of the foot as a unit of length can be traced back to ancient times, when it was used as a measure of length based on the human body. The word foot comes from the Old English word fot, which was derived from the ProtoGermanic word fotuz. It referred to the length of a human foot, which was about 280 millimeters. The foot was also used as a measure of length by other civilizations, such as the Romans, who used it as onesixteenth of a Roman pace or passus. The Roman foot was about 296 millimeters. The foot 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 foot remained as a derived unit in the imperial system, but it was no longer recommended for use in scientific and technical fields. Where Foot is UsedThe foot is a unit of length that is used for measuring short distances and dimensions, such as the height of a person or the width of a door. The foot is commonly used in everyday life, especially in countries that follow the US customary system. Some examples are:

In this article, we will explore how to convert foot to other units of length in the US customary system and the SI system. We will also provide 10 examples of conversion for each system. How to Convert Foot to Other Units of Length in the US Customary SystemThe US customary system is a system of measurement that uses units such as inch, yard, mile, ounce, pound, gallon, etc. The US customary system is based on the English system of measurement that was used before the adoption of the metric system. To convert foot to other units of length in the US customary system, we need to know the relationship between foot and other units. Here are some common units and their equivalent values in feet: To convert foot to any of these units, we need to multiply or divide by the appropriate factor. For example, to convert 10 feet to inches, we need to multiply by 12: 10 feet x 12 = 120 inches To convert 10 feet to miles, we need to divide by 5280: 10 feet / 5280 = 0.00189 miles To convert 10 feet to fathoms, we need to divide by 6: 10 feet / 6 = 1.667 fathoms To convert 10 feet to rods, we need to divide by 16.5: 10 feet / 16.5 = 0.606 rods How to Convert Foot to Other Units of Length in the SI SystemThe SI system (or International System of Units) is a system of measurement that uses units such as meter, kilogram, second, ampere, kelvin, mole, candela, etc. The SI system is based on the metric system that was developed in France in the late 18th century. To convert foot to other units of length in the SI system, we need to know the relationship between foot and meter. The meter is the base unit of length in the SI system and it is defined as “the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds.” One foot is equal to 0.3048 meters. To convert foot to any other unit of length in the SI system, we need to multiply or divide by the appropriate power of ten and add a prefix. Here are some common units and their equivalent values in meters: To convert foot to any of these units, we need to multiply by the appropriate factor and add a prefix. Español Russian Français
