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.
Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
