Earth Equatorial Radius

The Earth's equatorial radius is the distance from the center of the Earth to the equator. It represents the Earth's radius measured along the equatorial plane.

• 
  

  Its value is approximately 6,378.1 kilometers (about 3,963.2 miles).

  
  
• 
  

  The Earth is not a perfect sphere but an oblate spheroid, so the equatorial radius is slightly larger than the polar radius.

  
  
• 
  

  This radius is important for geodesy, satellite orbits, and mapping.

  
  

Key facts:

• 
  

  Equatorial radius ≈ 6,378.1 km

  
  
• 
  

  Larger than polar radius due to Earth's flattening at the poles

  
  
• 
  

  Used in Earth sciences, navigation, and space missions

  
  

Understanding the Earth's equatorial radius helps in accurate modeling of the planet’s shape and gravitational field.

Furlong

A furlong is a traditional unit of distance used primarily in agriculture and horse racing. It is equal to 220 yards, 660 feet, or 1/8 of a mile (approximately 201.168 meters).

The word "furlong" comes from the Old English words furh (furrow) and lang (long), originally referring to the length of a furrow in a 10-acre field. It was historically used in England to measure field lengths for plowing.

In modern times, the furlong is rarely used outside of horse racing, where race distances are still often given in furlongs, especially in the United Kingdom and the United States.

Conversions:

• 
  

  1 furlong = 660 feet

  
  
• 
  

  1 furlong = 220 yards

  
  
• 
  

  1 furlong ≈ 201.168 meters

  
  
• 
  

  8 furlongs = 1 mile

  
  

Although considered outdated for most uses, the furlong remains a culturally significant unit in some specific fields.
