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.
Link (Us Survey)
A U.S. survey link is a unit of length equal to 1/100 of a U.S. survey chain.
History/Origin
The U.S. survey link is based on the U.S. survey foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey link was used for land surveying in the United States.
