Centimeter

A centimeter (cm) is a unit of length in the metric system. It is commonly used to measure small objects or short distances. One centimeter is equal to one-hundredth of a meter, meaning 100 centimeters make 1 meter. In everyday life, centimeters are used to measure height, the size of books, or dimensions of furniture. For example, a pencil might be about 15 cm long. The symbol for centimeter is "cm", and it is widely used around the world, especially in countries that follow the metric system. Rulers and measuring tapes often include centimeter markings to help with precise measurements. The centimeter is a practical and easy-to-use unit that helps in getting accurate sizes for various items.

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.
