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 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.
