Decimeter
A decimeter (dm) is a unit of length in the metric system. It is equal to one-tenth of a meter, or 10 centimeters (1 dm = 0.1 m = 10 cm). While not as commonly used as centimeters or meters in everyday life, decimeters are still important in scientific and technical measurements. For example, a small book or a tablet might be about 2 to 3 decimeters long. The symbol for decimeter is "dm". Although it sits between the centimeter and meter in size, people often skip using decimeters and go directly from centimeters to meters. Still, it's a helpful unit when you need a mid-sized measurement.
Link (US Survey)
The US survey link is a unit of length used in the United States for land surveying, defined as exactly 7.92 US survey inches. Since one US survey inch is slightly longer than the international inch (due to the US survey foot), the US survey link is approximately 0.201168 meters.
It is part of the US survey system, derived from Gunter’s chain, which is divided into 100 links per chain (66 US survey feet). Links are used to measure small distances in surveying and land measurement.
Key facts:
1 US survey link = 7.92 US survey inches
1 US survey link ≈ 0.201168 meters
100 links = 1 US survey chain (66 US survey feet)
25 links = 1 US survey rod (16.5 US survey feet)
Though the US survey units are being phased out, the US survey link still appears in historical land records and legal surveying documents.
