Based on the formula P = F / S, it depends on the compressive force and surface area. The pressure force (F) in solids is equal to the weight of the solid body. The surface area (S) is also the contact area of the solid body. Since the contact area is inversely proportional to the contact area, the weight of the two objects with the same weight will be higher than the larger one. For example, hold the pin between your thumb and forefinger. The pain felt at the pointed end will be higher than the other end. The reason is that the pressure is higher since the surface area in the pointed end is smaller than the surface area of the other side. You can use our pressure units converter calculation tool if you want to convert between.
