I know that a scalar quantity only comprises of magnitude while a vector consist of both magnitude and direction.. But is there no definite formula to determine whether or not a quantity is a scalar or a vector.. or is there a list of scalars and vectors to show all quantities grouping under scalar n vector..?

Therefore, pressure is a scalar quantity, not a vector quantity. It has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface.
