Vara de Tarea

The vara de tarea is a traditional Spanish and Latin American unit of area used especially in land measurement and agriculture. It combines the vara, a unit of length, with the tarea, a unit of area.

• 
  

  The vara is roughly 33 inches (about 0.84 meters), though it varies by region.

  
  
• 
  

  A tarea typically refers to an area equal to 100 square varas, but this can differ locally.

  
  
• 
  

  Therefore, a vara de tarea is often used to express land area based on square varas.

  
  

This unit remains in use in some rural parts of Latin America for land deeds and agricultural measurements, reflecting historical Spanish colonial measurement systems.

Summary:

• 
  

  Vara ≈ 0.84 meters

  
  
• 
  

  Tarea ≈ 100 square varas (area)

  Vara de tarea = unit combining length and area for land measurement

  Common in Spanish-speaking countries’ historical land records

  
  

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.
