What do you mean "... based on"? The athmosperic pressure is "weight of air" and it can be measured. Strikly speaking: "force per unit area exerted against a surface by the weight of air above that surface at any given point" (wikipedia) Ap could be given in force/area units for example lb/sq ft, kg/sq meter etc.
