X-unit


The X-unit (symbol: xu) is a very small unit of length used primarily to measure wavelengths of X-rays and gamma rays. It was introduced in the early 20th century for precision measurements in X-ray crystallography.



  • 1 X-unit ≈ 0.1 picometers (pm) or 10⁻¹³ meters



  • It allows scientists to express extremely small wavelengths typical of X-rays, which are on the order of atomic spacing



  • The exact definition has varied historically, but the unit remains useful for comparing wavelengths in X-ray spectroscopy and crystallography



Though largely replaced by the picometer or ångström in modern usage, the X-unit played a crucial role in early developments of atomic-scale measurement.



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.
