Pressure - Wikipedia
WEBPressure is the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P. The IUPAC recommendation for pressure is a lower-case p. However, upper-case P is widely used.
What is pressure? (article) | Fluids | Khan Academy
WEBPressure is defined to be the amount of force exerted per area. P = F A. So to create a large amount of pressure, you can either exert a large force or exert a force over a small area (or do both). In other words, you might be safe lying on a bed of nails if the total surface area of all the nail tips together is large enough. Really?
