![]() Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. You can find metric conversion tables for SI units, as well as English units, currency, and other data. 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. So using the definition of parsec you can easily determine the distance in light years. We assume you are converting between light year and parsec.You can view more details on each measurement unit: light years or parsec The SI base unit for length is the metre. How many light years in 1 parsec The answer is 3.2615637967311. From Google I get: A parsec, or parallax second, is defined as 3.26 light-years. More information from the unit converter. One arcsecond is equal to 1/3600 of a degree, or about 4.8481368 rad in radians. One parsec represents the distance from the Sun to an astronomical object, such as a planet, a star, a moon, or an asteroid, which has a parallax angle equal to an arcsecond. ![]() 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). Dividing the former by the latter, we get 1 pc 1 ly 3.261564 1 pc 1 ly 3.261564. A parsec (pc) is about 30,856,775,814,671,900 meters, or approximately 3.09 × 10 km. The parsec (symbol pc) is a unit of length used in astronomy. ![]() Light year to Parsec, or enter any two units below: Enter two units to convert From: ![]() If you need to convert parsec to another compatible unit, please pick the one you need on the page below.
