Rod (US Survey)

The US survey rod is a unit of length used in U.S. land surveying. It is defined as exactly 16.5 US survey feet, which is slightly longer than the international foot. Since one US survey foot equals approximately 0.3048006096 meters, the US survey rod measures about 5.0292 meters.

The survey rod, also called a pole or perch, is historically significant in the U.S. Public Land Survey System and is used to measure land boundaries and distances.

Key facts:

• 
  

  1 US survey rod = 16.5 US survey feet

  
  
• 
  

  1 US survey rod ≈ 5.0292 meters

  
  
• 
  

  4 US survey rods = 1 US survey chain

  
  
•

Though the US survey foot and related units are being phased out in favor of international units, the US survey rod still appears in legal land descriptions and older surveying documents.

Barleycorn

A barleycorn is an old English unit of length, traditionally based on the length of a grain of barley. It is defined as exactly 1/3 of an inch or approximately 8.47 millimeters.

Historically, the barleycorn was used for measuring small lengths and was also the basis for the inch, which was originally considered to be three barleycorns long. It played a role in various traditional measurements, including shoe sizing in English-speaking countries, where shoe sizes were sometimes expressed in barleycorn units.

Although obsolete as a formal unit, the barleycorn remains culturally significant, especially in shoe sizing systems.
