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Although considered outdated for most uses, the furlong remains a culturally significant unit in some specific fields.


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.
