How to convert1 parsec (pc) = 3.08568E+16 meter (m). Parsec (pc) is a unit of Length used in Metric system. Meter (m) is a unit of Length used in Metric 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
Meter  Unit of Distance / LengthUnit Symbol / Abbreviation: m Where the unit used in the World: The meter is used as a unit to measure medium distances or lengths. Definition of the Unit: The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983). 1 m is equivalent to 3.28084 ft or 0.000621371 miles. History of the Unit: As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second. Where it's used: The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on). Equivalents in other units and scales:
1 m is equivalent to 3.28084 ft or 1.09361 yd. Español Russian Français
