Scaled-up conversion.
A parsec (parallax-arcsecond) is the distance at which 1 AU subtends an angle of 1 arcsecond. It equals 3.26 light years.
1 parsec = 3.26156 light years.
Proxima Centauri is 1.295 parsecs (4.224 light years) from Earth.
Parsecs relate directly to parallax measurements, the primary method for measuring stellar distances. They also simplify many astronomical calculations.
1 kiloparsec (kpc) = 1000 parsecs = 3261.56 light years. The Milky Way is about 30 kpc in diameter.
All conversions use exact international definitions, providing results accurate to floating-point precision (about 15 significant digits).
Yes, simply use the inverse formula or look for the reverse converter in our collection.
This conversion is commonly used in science, engineering, education, and professional applications requiring interstellar distance measurement.
This conversion uses internationally defined exact factors wherever possible. Any approximation is noted in the results.
Conversion factors are from NIST, BIPM (International Bureau of Weights and Measures), and ISO standards.
