Foot

A foot (plural: feet) is a unit of length commonly used in the United States, the United Kingdom, and some other countries. One foot equals 12 inches or about 0.3048 meters. Feet are often used to measure height, room dimensions, and short distances. For example, a person might be 5 feet 8 inches tall. The abbreviation for foot is "ft". Although many countries use the metric system, feet remain popular in daily life and construction in countries using the imperial system.

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.
