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.

Earth Polar Radius

The Earth's polar radius is the distance from the center of the Earth to the North or South Pole. It measures the Earth’s radius along its rotational axis.

• 
  

  Its value is approximately 6,356.8 kilometers (about 3,949.9 miles).

  
  
• 
  

  The Earth is an oblate spheroid, so the polar radius is slightly shorter than the equatorial radius due to the planet's flattening at the poles.

  
  
• 
  

  This measurement is crucial for geodesy, understanding Earth’s shape, and satellite navigation.

  
  

Key facts:

• 
  

  Polar radius ≈ 6,356.8 km

  
  
• 
  

  Smaller than equatorial radius by about 21.3 km

  
  
• 
  

  Important for precise Earth modeling and mapping

  
  

The difference between the polar and equatorial radius reflects the Earth’s rotation and its effect on the planet’s shape.
