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.
Yard
A yard is a unit of length in the imperial and US customary systems of measurement, equal to 3 feet or 36 inches.
History/Origin
The origin of the yard is uncertain, but it is believed to have been derived from the length of a man's belt or girdle. The yard was standardized as part of the English (and later British Imperial) system of units.
Current Use
