Web ResultPressure 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?]

Web ResultMay 7, 2019 · In science, pressure is a measurement of the force per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/m 2 (newtons per meter squared). Basic Example. If you had 1 newton (1 N) of force distributed over 1 square meter (1 m 2 ), then the result is 1 N/1 m 2 = 1 N/m 2 = 1 Pa.
