Pressure and stress have the same unit (and dimension),although they are not the same physical quantity. Why?

(N/A) Pressure is defined as the normal force applied per unit area,which is a scalar quantity because it acts equally in all directions at a point in a fluid.
Stress is defined as the restoring force per unit area developed within a material due to an external deforming force. Since stress depends on the direction of the applied force and the orientation of the surface,it is a tensor quantity (often treated as a vector in basic contexts) because it has both magnitude and direction.
