Pressure = force/area
SI units for force = newtons
SI units for area = square meters
So pressure = n/m^2
The pascal (pronounced pass-KAL and abbreviated Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist Blaise Pascal. One pascal is equivalent to one newton (1 N) of force applied over an area of one meter squared (1 m2).
