Convert inch to Earth equatorial radius Online | Free Length Converter

Inch

An inch is a unit of length used primarily in the imperial and U.S. customary systems. It is commonly used in countries like the United States, Canada, and the UK for measuring shorter lengths. One inch equals 2.54 centimeters. There are 12 inches in a foot. Inches are often used to measure things like screen sizes, paper dimensions, or body measurements. For example, a standard smartphone screen might be about 6 inches. The symbol for inch is "in" or a double quote mark (″). Rulers, measuring tapes, and toolkits often include inches for easy reference. Although the metric system is more widely used globally, inches remain common in certain industries and countries for specific applications.

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.
