A light year is the distance that light will travel in one year. A parsec is short for parallax second, which is also a measure of distance.Answer 1 Parsec = 3.26163626 light years 1 light year = 0.30659458 Parsecs
"Light-year" and "parsec" are two units of length used in astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.
Three units are commonly used in astronomy - the astronomical unit; the light-year; and the parsec.
The standard unit of length is the meter, and any multiple and submultiple such as kilometer and millimeter. Nonstandard units include foot, inch, mile, light-year, parsec, astronomical unit.

The usual units of measure are; Astronomical Unit (AU) Light year Parsec
The astronomical unit is the mean distance from Earth to Sun. It is commonly used for distances in the Solar System. This way, it is easier to imagine the distances, since the meter or kilometer are very small units (an astronomical unit is about 150 million km, or 150 billion meters), and the light year and the parsec are very large units (a light-year is about 63,000 astronomical units, the parsec is even larger). Light-minutes or light-hours might be used instead, within the Solar System, but the astronomical unit has become quite popular.
An astronomical unit (AU) is a unit of measurement used in astronomy that is equal to the average distance between the Earth and the Sun, about 93 million miles. A parsec is a unit of measurement used to describe astronomical distances, equal to about 3.26 light-years or 206,265 AU.
The astronomical unit called a parsec is based on the idea of parallax.

The official unit for length is the meter. The kilometer (1000 meters) is often used in practice. Larger distances/lengths are often expressed in meters or kilometers; if the numbers are very large, scientific notation is used. On the other hand, in astronomy the following non-SI units are often used for very large distances:The astronomical unit, which is the average distance from Sun to Earth. Approximately 150 million km.The light-year, the distance light travels in a year. Approximately 9.5 x 1012 km.The parsec - a hypothetical star at that distance would have a parallax of 1 arc-second (all stars except the Sun are at a distance of more than 1 parsec). 1 parsec is approximately 3.26 light-years. Prefixes such as kilo- and mega- are sometimes used with parsec.

We use AU when we talk about distances between objects WITHIN the solar system. One "parsec", or "parallax-second of arc", is the distance that an object would be (from Earth) if we measure a one second of arc difference in the relative direction of a "nearby" object, measured from one side of the Earth's orbit to the other. That gives us a baseline distance of 2 AU, about 300 million km or 186 million miles. You can calculate the distance of one parsec using trigonometry; the base of the triangle is 2AU, and the opposite angle is 1 second of arc (1/3600th of a degree). Roughly, one parsec is about 3.26 light years. We use parsecs to measure distance between stars, or between objects in the galaxy.
