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.
Alen or aln is a traditional Scandinavian unit of distance similar to the north German elle: roughly 60 centimeters. The Danish alen, also used in Norway, was equal to 62.77 centimeters (2 Danish fod). The Swedish aln was 59.38 centimeters.
In relation to the base unit of [length] => (meters), 1 Bohr Radius (Bohr) is equal to 5.29177E-11 meters, while 1 Alens (aln) = 0.593778 meters.| 308700 Bohr Radius | to common length units |
