Pressure is defined as force per unit area (P = F/A). It is generally expressed in pounds per square inch (psi) or pounds per square foot (psf). The pressure on the bottom of a tank having a base area of one square foot and filled to a depth of one foot with water having a specific weight of 62.4 lb/ft3 is P = F/A = 62.4 lb/1 ft2 = 62.4 psf. In this case the force F was the weight of the one cubic foot of water and this weight rested on the one square foot area.
