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.


Roman Actus


The actus was an ancient Roman unit of length used primarily in land measurement. It is approximately 120 Roman feet, which equals about 35.5 meters (around 116.5 feet).


The actus was often used to define dimensions of fields and plots of land. It was also part of Roman surveying practices, helping organize land division and property boundaries.


Key facts:



  • 1 actus = 120 Roman feet ≈ 35.5 meters



  • Used in Roman land surveying and agriculture



  • Essential for measuring fields and agricultural plots



  • Reflects the Roman emphasis on precise land division



The actus highlights the sophistication of Roman engineering and property management in their time.
