Learn how to calculate pressure using the formula P = F / A, where P is pressure , F is force, and A is area. Find out the units of pressure , the hydrostatic pressure formula , and the applications of pressure in physics, engineering, and meteorology. Pressure is a fundamental concept in physics and fluid mechanics that plays a crucial role in understanding the behavior of gases, liquids, and solids. It is defined as the force or thrust exerted per unit area on a surface. In simpler terms, pressure measures how much force is distributed over a given area. Our pressure calculator uses the straightforward pressure formula below: p = F / A, where: p – Pressure ; F – Force; and A – Area of the surface. This pressure definition relates to the force applied perpendicularly to the object's surface. It would help if you remembered that pressure is a scalar, and therefore it has no direction (as opposed to the force). Pressure is one of the most important concepts in physics. While you'll undoubtedly have some idea of what pressure is from things like atmospheric pressure readings given in weather reports or water pressure in your home's heating system, when you're studying physics, the details really matter. Learning the precise definition of pressure helps you understand key concepts related to gases, thermodynamics, buoyancy and much more.
