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.
Nanometer
A nanometer (nm) is an incredibly small unit of length in the metric system. It equals one-billionth of a meter (0.000000001 meters). Nanometers are used to measure things at the atomic and molecular scale, like the size of viruses, DNA strands, or the width of a few atoms. The symbol for nanometer is "nm". This unit is essential in fields like nanotechnology, physics, and chemistry, where scientists work with materials and particles too tiny to see with regular microscopes. Understanding measurements in nanometers helps researchers develop new materials, medicines, and electronic devices.
