Attometer


An attometer (am) is a unit of length in the metric system, equal to one-quintillionth of a meter (1 am = 10โปยนโธ meters). This unit is extremely small, even smaller than a femtometer, and is used in theoretical physics to describe distances at the quantum level, such as within particles or in advanced models of spacetime. However, attometers are rarely used in practice because most known physical structures, including subatomic particles, are still larger than this. The attometer mainly appears in scientific equations or hypotheses dealing with concepts beyond current experimental capabilities.




Fathom (US Survey)


The fathom (US survey) is a unit of length used in U.S. surveying and nautical contexts, defined as exactly 6 US survey feet. Since one US survey foot is approximately 0.3048006096 meters, the US survey fathom measures about 1.828804 meters.


Like the international fathom, it is primarily used to measure water depths and underwater distances in marine navigation and surveying.


Key details:



  • 1 US survey fathom = 6 US survey feet



  • 1 US survey fathom โ‰ˆ 1.828804 meters



  • 1 fathom = 2 yards



Though the difference between the US survey fathom and the international fathom is very small, the US survey units are being phased out in favor of international standards, but they still appear in some legal and historical surveying documents.
