Astronomical Unit
An astronomical unit (AU) is a unit of distance used in astronomy to describe the average distance between the Earth and the Sun. It equals about 149.6 million kilometers (or about 93 million miles). The AU is useful for measuring distances within our solar system, such as the distance from Earth to other planets. For example, Mars is about 1.5 AU from the Sun. Using the AU makes it easier to understand and compare distances between planets without dealing with very large numbers. The symbol for astronomical unit is "AU".
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.
