Pressure is force divided by the area it acts on — which is why the same body weight keeps you on top of snow in snowshoes yet drives a thumbtack into wood. Shrink the area a thousandfold and the pressure grows a thousandfold. One pascal is one newton per square metre; atmospheric pressure is about 101 kPa.
