Point

A point is a unit of length used mainly in typography to measure font size, line spacing, and other elements of printed text. It is defined as 1/72 of an inch, which is approximately 0.3528 millimeters.

Key facts:

• 
  

  1 point = 1/72 inch ≈ 0.3528 mm

  
  
• 
  

  12 points = 1 pica

  
  
• 
  

  Used universally in typesetting, desktop publishing, and graphic design

  
  
• 
  

  Measures font sizes, leading (line spacing), and other typographic details

  
  

The point system helps designers and printers maintain precise and consistent text layouts across various media.

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.
