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.
Attometer
An attometer is a unit of length in the metric system equal to 10^-18 meters.
History/Origin
The prefix "atto-" for 10^-18 was adopted by the CGPM (General Conference on Weights and Measures) in 1964.
Current Use
The attometer is used in high-energy physics to describe the scales relevant to quarks and leptons.
