Span (Cloth)


A span is an old unit of length based on the distance between the tip of the thumb and the tip of the little finger of a fully extended hand. Traditionally, it measures about 9 inches or 22.86 centimeters.


In the context of cloth and textiles, the span was used as a convenient, informal measure to estimate small lengths of fabric before standardized rulers became widespread. It was helpful for tailors and traders to quickly gauge lengths during measuring and cutting.


While the span is largely obsolete as a formal unit today, it reflects historical measurement practices tied closely to the human body, similar to the cubit or hand.


Summary:



  • 1 span β‰ˆ 9 inches (22.86 cm)



  • Based on the hand’s spread



  • Used historically in cloth measurement and tailoring



  • Now mostly of historical and cultural interest


Link (US Survey)


The US survey link is a unit of length used in the United States for land surveying, defined as exactly 7.92 US survey inches. Since one US survey inch is slightly longer than the international inch (due to the US survey foot), the US survey link is approximately 0.201168 meters.


It is part of the US survey system, derived from Gunter’s chain, which is divided into 100 links per chain (66 US survey feet). Links are used to measure small distances in surveying and land measurement.


Key facts:



  • 1 US survey link = 7.92 US survey inches



  • 1 US survey link β‰ˆ 0.201168 meters



  • 100 links = 1 US survey chain (66 US survey feet)



  • 25 links = 1 US survey rod (16.5 US survey feet)



Though the US survey units are being phased out, the US survey link still appears in historical land records and legal surveying documents.
