How can we tell from Ka and Kb that the acid/base is strong or weak?

If the Ka or Kb is greater than 10^3, then it is a strong acid or base. If the Ka or Kb is less than 10^-3, then it is a weak acid or weak base

Ka reflects how much the acid will disassociate in reaction so a high Ka(higher than 1000) will indicate it being a strong acid and a low Ka(lower than .001) will indicate it being a weak acid.
