Kilometer

A kilometer (km) is a unit of length in the metric system, used to measure long distances. One kilometer equals 1,000 meters or about 0.62 miles. Kilometers are commonly used to measure distances between cities, in road signs, and in running or walking events. For example, a marathon is 42.195 kilometers long. The symbol for kilometer is "km". Most countries around the world use kilometers instead of miles for speed and distance, especially in transportation. Because it covers a large distance, the kilometer is not used for measuring small objects but is perfect for travel and mapping.

Chain (US Survey)

The US survey chain is a unit of length used historically in land surveying in the United States. It is defined as exactly 66 US survey feet, which is slightly longer than the international foot. Since one US survey foot equals about 0.3048006096 meters, the US survey chain is approximately 20.11684 meters long.

Like the standard chain, it is divided into 100 links, each measuring 0.66 US survey feet. The US survey chain was widely used in the Public Land Survey System to measure land parcels and boundaries.

Key facts:

• 
  

  1 US survey chain = 66 US survey feet

  
  
• 
  

  1 US survey chain ≈ 20.11684 meters

  
  
• 
  

  10 US survey chains = 1 furlong

  
  
• 
  

  80 US survey chains = 1 US survey mile

  
  

Though the US survey foot and chain are being phased out in favor of international units, the US survey chain still appears in historical land records and some legal contexts.
