A rack unit (abbreviated U or RU) is a unit of measure defined as 1.75 inches (44.45 mm). It is most frequently used as a measurement of the overall height of 19-inch and ..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.
In relation to the base unit of [length] => (meters), 1 Rack Unit (ru) is equal to 0.04445 meters, while 1 Bohr Radius (Bohr) = 5.29177E-11 meters.2749311288 Rack Unit | to common length units |
