How to convert

1 meter (m) = 3.24078E-17 parsec (pc). Meter (m) is a unit of Length used in Metric system. Parsec (pc) is a unit of Length used in Metric system.

Meter - Unit of Distance / Length

Unit Symbol / Abbreviation: m

Where the unit used in the World:

The meter is used as a unit to measure medium distances or lengths.
It's a standard measure for short distances (up to 1 km long), in real estate and construction, supply materials, vehicle and aircraft dimensions, short geographical distances and directions in most countries excluding the USA where foot and yard are still widely used for this purpose.
The meter is widely used in most countries and is the official unit for medium lengths and distances (for example, road signs in continental Europe show maximum vehicle hight in meters). Primary exceptions are the United States of America, and some countries where feet and yards are used in limited extent: the United Kingdom and Canada, where the yard remains in limited use as a part of imperial system (for example, yards are used on road signs for shorter distances in the United Kingdom and feet are widely used in construction and real estate in Canada).

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 krypton-86. 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 = 1000 millimeters (mm)
  • 1 m = 100 centimeters (cm)
  • 1 m = 10 decimeters (dm)
  • 1 m = 0.001 kilometers (km)
  • 1 m = 3.28084 feet (ft)
  • 1 megameter = 1000000 m
  • 1 gigameter = 1000000000 m
  • Units of length in the metric SI system are based on multiples or fractions of a meter.
  • There are measurements of length/distance in the metric SI system greater than a meter that can be expressed in terms of metres.

1 m is equivalent to 3.28084 ft or 1.09361 yd.

The meter is a unit of length in the metric SI system and is 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).

Meters also can be marked as metres (in British English spelling).

Parsec: A Unit of Length

A 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 parsec

The 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 parsec

The 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 parsec

To convert parsecs to other units of length, we can use the following conversion factors:

  • 1 pc = 3.0857 × 10^16 m
  • 1 pc = 1.9174 × 10^13 mi
  • 1 pc = 2.06265 × 10^5 au
  • 1 pc = 3.26156 ly

To convert other units of length to parsecs, we can use the inverse of these conversion factors:

  • 1 m = 3.24078 × 10^-17 pc
  • 1 mi = 5.21553 × 10^-14 pc
  • 1 au = 4.84814 × 10^-6 pc
  • 1 ly = 0.306601 pc

Where parsec is used

The 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 nearest star to the Sun, Proxima Centauri, is about 1.3 pc away.
  • The center of our galaxy, the Milky Way, is about 8 kpc away.
  • The nearest galaxy to ours, Andromeda, is about 780 kpc away.
  • The most distant quasar known, ULAS J1342+0928, is about 8.8 Gpc away.

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 units

Here are some examples of converting parsecs to other units of length:

  • How many meters are in one parsec?

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

  • How many miles are in 10 parsecs?

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

  • How many astronomical units are in 0.01 parsecs?

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

  • How many light-years are in 100 parsecs?

To convert 100 parsecs to light-years, we multiply by the conversion factor:

100 pc × 3.26156 ly/pc = 326.156 ly

  • How many parsecs are in one meter?

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

  • How many parsecs are in one mile?

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

  • How many parsecs are in one astronomical unit?

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

  • How many parsecs are in one light-year?

To convert one light-year to parsecs, we divide by the conversion factor:

1 ly / (3.26156 ly/pc) = 0.306601 pc
