1)Pressure represent intensity of external forces acting at a point but stress represent intensity of internal resisting forces develop at a point.
2)Pressure is always acts normal to the surface but stress may also act either normal or parallel to the surface.
3)Magnitude of pressure at a point in all directions remain same but magnitude of stress at a point in all the directions are unequal.
4)Pressure can be measured by using measuring device like pressure gauge but stress can't be measure directly by using any device.
