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.

Twip

A twip (short for twentieth of a point) is a very small unit of length used in digital typography and computer graphics. It equals 1/20 of a typographic point, or 1/1440 of an inch.

Key facts:

• 
  

  1 twip = 1/20 point = 1/1440 inch ≈ 0.01764 millimeters

  
  
• 
  

  Used in software and digital layout to specify very fine measurements for text, spacing, and graphics

  
  
• 
  

  Helps achieve high precision in formatting and display, especially in word processors and graphic design programs

  
  

Twips allow for detailed control over layout and formatting beyond what whole points can provide, ensuring smooth and precise rendering on screens and printers.
