The greater the $K_{a}$ $K_a$ value for an acid is relative to the strength of the acid, or the magnitude at which it will disassociate in water.

The closer the $K_{a}$ $K_a$ value is to one the stronger it is (the term "strong acid" means that it completely disassociates).

If you can remember the 6 strong acids you'll know that all other acids are weak:
$H C l$ $HCl$
$H B r$ $HBr$
$H I$ $HI$
$H_{2} S O_{4}$ $H_2SO_4$
$H C l O_{4}$ $HClO_4$
$H N O_{3}$ $HNO_3$
