The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. However, that distance varies as Earth orbits the Sun, f ..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 Astronomical Unit (au) is equal to 149597870700 meters, while 1 Bohr Radius (Bohr) = 5.29177E-11 meters.| 1 Astronomical Unit | to common length units |
