The formula for pressure is

P = F/A

In this equation, P stands for pressure while F stands for force and A stands for area.  Pressure is typically measured in a unit called the Pascal.

So what this means is that the amount of pressure that is exerted on an area is determined by the size of that area and by the amount of force that is pressing against it.

Therefore, if you have a given amount of force, you will have more pressure if it presses down on a small area than if it presses down on a large area.
