Answer

The strength of a base measures its capacity of dissociating in water, and therefore, producing $[OH^-]$ and a conjugate acid $([B^+])$. Bases that are capable of totally dissociating in water are called "strong bases". But other bases, like $NH_3$, only dissociate in a certain value (not 100%), that depends on the concentrations, and can be calculated by the formula: $Kb = \frac{[B^+][OH^-]}{[BOH]}$ Where each base has its $Kb$, that can be found in tables, books or the internet.
