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.
Foot (Us Survey)
The U.S. survey foot was a unit of length defined as exactly 1200/3937 meters.
History/Origin
The U.S. survey foot was used for land surveying in the United States for most of the 20th century. Its use was officially phased out in 2022 to standardize with the international foot.
Current Use
The U.S. survey foot is now an obsolete unit.
