Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−¹·s−²). Pascal is a so-called coherent derived unit in the SI with a special name and symbol.
