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.
A unit of length equal to one thousandth (10−3) of an inch (0.0254 millimeter = 0.0000254 meter), used, for example, to specify the diameter of wire or the thickness of materials sold in sheets. A mil also called a thousandth of an inch, or thou.
In relation to the base unit of [length] => (meters), 1 Bohr Radius (Bohr) is equal to 5.29177E-11 meters, while 1 Mils (mil) = 2.54E-5 meters.| 438500 Bohr Radius | to common length units |
