La pression atmospherique est la pression de l'air qui nous entoue.
Au niveau de la mer (altitude 0 metre) ,la pression atmospherique moyenne est
Patm =1015hPa=101500Pa=1,015 Bar
a      1Bar =100000Pa                 -5
a        5                1Pa=10 Bar
a     =10  Pa

  Lapression P exercee par une force pressante F sur une surface pressee S est egalea:
    
    
    P=F/S                 P+F/S
  INTERNATIONAL           INDUSTRIEL
  P=pression en Pa        P=pression en bar
  F=force en newton       F=force en daN
  S=surface en m2         S=surface en cm2
