Convert mile (statute) to chain (US survey) Online | Free Length Converter

A statute mile is a unit of length commonly used in the United States and the United Kingdom. It is officially defined as 5,280 feet or 1,609.344 meters. The term "statute mile" distinguishes it from other types of miles, such as the nautical mile. The origin of the statute mile dates back to an Act of Parliament in England in 1593, which standardized the length of the mile. It is primarily used for measuring distances on land, such as in road signs, speed limits, and maps. While many countries have adopted the metric system, the statute mile remains in everyday use in a few countries. In contrast to the nautical mile, which is used for air and sea navigation, the statute mile is mainly applied in land-based contexts. It is also used to calculate speed in miles per hour (mph), especially for vehicles and road travel.

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.
