The mile (abbreviation: mi) is a unit of distance on land in English-speaking countries equal to 5280 feet, or 1760 yards (1.609 kilometers). The mile was usually abbreviate ..more definition+
The Bohr radius (a0 or rBohr) is a physical constant, approximately equal to the most probable distance between the proton and electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.2917721067×10^−11 m.
