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 β‰ˆ 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.

Cubit (UK)


The cubit is an ancient unit of length based on the distance from the elbow to the tip of the middle finger. In the UK, the cubit varied historically but was generally considered to be about 18 inches (approximately 45.72 centimeters).


The cubit was used in medieval England and earlier times for measuring lengths, especially in construction and tailoring. It’s one of the oldest recorded units of measurement, with origins in ancient civilizations like Egypt and Mesopotamia.


Though obsolete in modern measurement systems, the cubit remains important in historical and archaeological contexts, reflecting early human methods of standardizing length based on the human body.
