Pressure depends upon the factors that follows:-. (1)It depends on force applied. (2)Area over in which force acts. The same force can produce different pressure depending upon area in which it acts. When the force acts over a large area,the pressure produced is less.
Pressure and stress have the same units: pounds per square inch (psi) or newtons per square meter (N/m^2) also known as pascal (Pa). Pressure is a force per unit area typically used inside a fluid (liquid or gas) and is the same in all directions at a point inside the fluid. Stress is also force per unit area but is typically used inside solids. The difference is that the stress can be different in different directions inside the solid.
