How to convert1 lightyear (ly) = 0.306594845 parsec (pc). Lightyear (ly) is a unit of Length used in Metric system. Parsec (pc) is a unit of Length used in Metric system. Lightyear: A Unit of LengthThe lightyear is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46 × 10^^{12} km), or 5.88 trillion miles (5.88 × 10^^{12} mi). As defined by the International Astronomical Union (IAU), a lightyear is the distance that light travels in a vacuum in one Julian year (365.25 days). The lightyear is most often used when expressing distances to stars and other distances on a galactic scale, especially in nonspecialist contexts and popular science publications. In this article, we will explore the definition, history, usage and conversion of the lightyear as a unit of length. Example Conversions of Lightyear to Other UnitsThe lightyear can be converted to other units of length by using different factors and formulas. Here are some examples of conversion for different types of units:
1 ly × 9.46 × 10^^{12} = 9.46 × 10^^{12} km
1 ly × 5.88 × 10^^{12} = 5.88 × 10^^{12} mi
1 ly × 63,241 = 63,241 AU
1 ly / 3.26 = 0.31 pc
1 km / 9.46 × 10^12 = 1.06 × 10^^{13} ly
1 mi / 5.88 × 10^12 = 1.70 × 10^^{13} ly
1 AU / 63,241 = 1.58 × 10^^{5} ly
1 pc × 3.26 = 3.26 ly Parsec: A Unit of LengthA 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 lightyears 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. How to convert parsecTo convert parsecs to other units of length, we can use the following conversion factors:
To convert other units of length to parsecs, we can use the inverse of these conversion factors:
To convert one lightyear to parsecs, we divide by the conversion factor: 1 ly / (3.26156 ly/pc) = 0.306601 pc Español Russian Français
