Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. The formula used in parsecs to light years conversion is 1 Parsec 3. You can find metric conversion tables for SI units, as well as English units, currency, and other data. Parsecs to kilometers conversion factor 1 parsec is equal to 30856778200000. Alternatively, you can enter the value into the right To box and read the result of conversion in the From and Result boxes. The result will appear in the Result box and in the To box. Enter the value (for example, 15) into the left From box. More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely far away from any gravitational or magnetic fields, in one Julian year (365.25 days of 86400 seconds each).Ĭ provides an online conversion calculator for all types of measurement units. Select the unit to convert to in the right box containing the list of units. It stands for "parallax of one arc second", and is approximately 19,131,554,073,600 (19 trillion) miles.Ī light year, abbreviated ly, is the distance light travels in one year: roughly 9.46 × 1012 kilometres (9.46 petametres, or about 5.88 × 1012 (nearly six trillion) miles). The parsec (symbol pc) is a unit of length used in astronomy. To convert all types of measurement units, you can used this tool. In other words, 1 light year is 3261564 times smaller than a megaparsec. ![]() In other words, 1 parsec is 306602 times. The formula used in light years to megaparsecs conversion is 1 Light Year 3.0660139378555E-07 Megaparsec. The formula used in parsecs to million light years conversion is 1 Parsec 3.26156377716744E-06 Million Light Year. a The parsec unit is obtained by the use of parallax and trigonometry, and is. 30.9 trillion kilometres (19.2 trillion miles ). The parallax angle is found by measuring the parallax motion (or apparent movement of a star relative to stable, more distant stars) when the star is observed from opposite sides of the Sun (an interval of six months on Earth). ly stands for light years and Mpc stands for megaparsecs. The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years or 206,265 astronomical units (AU), i.e. The definition of a parsec is as follows: A parsec is the distance from the sun to an astronomical object which has a parallax angle of one arcsecond (1/3600 of a degree). With accuracy to six decimal places, one parsec is equal to 3.261563 light years. ![]() The SI prefix "mega" represents a factor of ![]() Light years to megaparsecs, or enter any two units below: Enter two units to convert From: You can do the reverse unit conversion from 2 Light years 0.6132 Parsec: 20 Light years 6.1319 Parsec: 5000 Light years 1532.97 Parsec: 3 Light years 0.9198 Parsec: 30 Light years 9.1978 Parsec: 10000 Light years 3065.95 Parsec: 4 Light years 1.2264 Parsec: 40 Light years 12.2638 Parsec: 25000 Light years 7664.87 Parsec: 5 Light years 1.533 Parsec: 50 Light years 15.
