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.
In relation to the base unit of [length] => (meters), 1 Bohr Radius (Bohr) is equal to 5.29177E-11 meters, while 1 Microinches (μin) = 2.54E-8 meters.| 73 Bohr Radius | to common length units |
