A variant of the point, equal to 0.3759 mm, or 1/72 of a French Royal inch (27.07 mm), or about 1/68 inch. Didot points are used in Europe. This unit is named after the French printer François Ambroise Didot (1730 - 1804) who defined the "point-based" typographical measurement system.
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 Didot Points (didot point) is equal to 0.000375972222 meters, while 1 Bohr Radius (Bohr) = 5.29177E-11 meters.4501000000000 Didot Points | to common length units |
