Dekameter
A dekameter (dam) is a unit of length in the metric system, equal to 10 meters. It sits between a meter and a hectometer in size. Although it is an official part of the metric system, the dekameter is rarely used in everyday life, education, or even science. For example, a small swimming pool might be around 2 dekameters long. The symbol for dekameter is "dam". Since most people prefer using meters or kilometers, the dekameter is more of a theoretical unit used mainly for teaching the structure of the metric system.
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
40 US survey rods = 1 US survey furlong
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.
