A twip (abbreviating "twentieth of a point", "twentieth of an inch point") is a typographical measurement, defined as 1/20 of a typographical point. One twip is 1/1440 inch o ..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 Twips (twip) is equal to 1.7639E-5 meters, while 1 Bohr Radius (Bohr) = 5.29177E-11 meters.| 221000000 Twips | to common length units |
