Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distribute.
The SI unit for pressure is the pascal, equal to one newton per square metre. Other units of pressure, such as pounds per square inch (Ibf/in2), bar and atmosphere, are also in common use.
