Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. One of the most important of these is the astronomical unit. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".Ĭonversion calculator for all types of measurement units. The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles). It is approximately equal to the mean distance between the Earth and Sun. It stands for "parallax of one arc second", and is approximately 19,131,554,073,600 (19 trillion) miles. The parsec (symbol pc) is a unit of length used in astronomy. The unit has its origins in one of the first methods of. But - how long is a parsec in more familiar distance units Lets see if we can derive this in. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). Accepts different units for each dimension. Basically, its a unit of length used to measure the astronomically large distances between objects beyond our Solar System. The unit was likely named by a British astronomer, Herbert Hall Turner, who suggested the unit of. 1AU/tan(1) is 1/4.8481368x10-6, which yields 206264.8 AU/parsec. Calculate the volume of a rectangular shaped box, solid or space from the dimensions of length, width and height. Combining it with the 'atto-' prefix (×10 18) yields attoparsec (apc), a conveniently human-scaled unit of about 3.086 centimetres (1.215 in) that is used only humorously. A unit of astronomical length based on the distance from Earth at which stellar parallax is one second of arc and equal to 3.258 light-years. A parsec is approximately 3.26 light-years or about 3.086×10 16 m (1.917×10 13 mi ). parsec synonyms, parsec pronunciation, parsec translation, English dictionary definition of parsec. The term parsec is a portmanteau a combination of two words: Parallax and Arcsecond. Parsecs are used in astronomy to measure interstellar distances. more definition+In relation to the base unit of => (meters), 1 Parsecs (pc) is equal to 3.0856775814914E+16 meters, while 1 Meters (m) = 1 meters.You can do the reverse unit conversion fromĪU to parsec, or enter any two units below: Enter two units to convert From: To be exact, a parsec is a unit of distance that’s equal to 19 trillion miles: 1 parsec 3.26 light-years 19 trillion miles. The meter, equal to 100 centimeters or approxi. The meter (abbreviation = m, symbol = m), or metre (British spelling) is the fundamental unit of length in the metric system. One parsec is the distance at which one astronomical unit sub. How to convert Parsecs to Meters (pc to m)?ġ x 3.0856775814914E+16 m = 3.0856775814914E+16 Meters.Īlways check the results rounding errors may occur.Ī parsec (symbol: pc) is a unit of length used to measure large distances to objects outside our Solar System. The reason why the parsec is used is the way we measure the distance. It stands for 'parallax of one arc second', and is approximately 19,131,554,073,600 (19 trillion) miles. The base unit for length is meters (SI Unit) Media in category 'Parsec (unit of length)' The following 36 files are in this category, out of 36 total. the length of a parsec has since been calculated as 3.26 light years or 30.9 trillion km. The parsec (symbol pc) is a unit of length used in astronomy.
