Chain (Us Survey)
A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.
History/Origin
The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey chain was used for land surveying in the United States.
Nanometer
A nanometer is a unit of length in the metric system, equal to one billionth of a meter.
History/Origin
The term “nanometer” gained prominence in the late 20th century with the advent of nanotechnology and the development of microscopes capable of observing objects at that scale.
Current Use
The nanometer is commonly used to express dimensions on an atomic and molecular scale. It is used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum and in the field of nanotechnology.
