Angstrom
The angstrom is a unit of length equal to 10⁻¹⁰ meters. It is not an SI unit.
History/Origin
In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight in which he expressed the wavelengths in multiples of one ten-millionth of a millimeter. The unit was named after him.
Current Use
The angstrom is used to express the sizes of atoms, molecules, and the wavelengths of electromagnetic radiation, particularly in the fields of chemistry, spectroscopy, and crystallography.
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.
