Astronomical Unit (a.u.) of Length


The astronomical unit (a.u.) is a unit of length used primarily in astronomy to describe distances within our solar system. It is defined as the average distance between the Earth and the Sun.


Key facts:



  • 1 astronomical unit ≈ 149,597,870.7 kilometers (about 93 million miles)



  • Used to measure distances between planets and other objects in the solar system



  • Provides a convenient scale for expressing space distances that are too large for kilometers but too small for light-years



The astronomical unit helps astronomers communicate and calculate orbits, planetary positions, and space missions with clarity and precision.



Link


A link is a traditional unit of length used primarily in land surveying. It is defined as exactly 7.92 inches or approximately 20.1168 centimeters.


The link originated from Gunter's chain, a 66-foot measuring device introduced in 1620 by English mathematician Edmund Gunter. This chain was divided into 100 equal parts, each measuring one link. The link became a standard unit in English-speaking countries for surveying and land measurement.


Key Facts:



  • 1 link = 7.92 inches



  • 1 link ≈ 20.1168 cm



  • 25 links = 1 rod (16.5 feet)



  • 100 links = 1 chain (66 feet)



  • 1,000 links = 1 furlong (660 feet)



While the link has largely fallen out of general use, it remains a part of historical surveying practices and is still referenced in some legal and cadastral documents.
