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.


Twip


A twip (short for twentieth of a point) is a very small unit of length used in digital typography and computer graphics. It equals 1/20 of a typographic point, or 1/1440 of an inch.


Key facts:



  • 1 twip = 1/20 point = 1/1440 inch ≈ 0.01764 millimeters



  • Used in software and digital layout to specify very fine measurements for text, spacing, and graphics



  • Helps achieve high precision in formatting and display, especially in word processors and graphic design programs



Twips allow for detailed control over layout and formatting beyond what whole points can provide, ensuring smooth and precise rendering on screens and printers.
