Fathom (Us Survey)
A U.S. survey fathom is a unit of length equal to 6 U.S. survey feet.
History/Origin
The U.S. survey fathom 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 fathom was used in surveying in the United States.
A.u. Of Length
The atomic unit of length, also known as the Bohr radius (a₀), is approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
