Centiinch

A centiinch is a very small unit of length equal to one-hundredth of an inch (0.01 inch). It is not commonly used in everyday measurement but may appear in fields requiring precise fractional measurements based on the inch.

Key details:

• 
  

  1 centiinch = 0.01 inch

  
  
• 
  

  Equivalent to 0.254 millimeters

  
  
• 
  

  Used for fine measurements where inch subdivisions are preferred

The centiinch allows for more detailed measurements within the inch system, similar to how centimeters subdivide a meter.

Mile (US Survey)

The US survey mile is a unit of length used in land surveying in the United States. It is defined as exactly 5,280 survey feet, with one survey foot equal to 1200/3937 meters (approximately 0.3048006096 meters). This makes the US survey mile equal to about 1,609.3472 meters, slightly longer than the international (statute) mile, which is exactly 1,609.344 meters.

The US survey mile was established to maintain consistency with older land measurement systems based on the Mendenhall Order of 1893. It was commonly used in mapping, legal land descriptions, and public land surveys.

Although the difference between the survey and statute mile is very small (about 3.2 millimeters), it can be significant over large distances. As of 2023, the U.S. has officially retired the survey foot (and survey mile) for most applications, favoring the international foot and mile to standardize measurements.
