Pressure measurements refer to the quantification of force exerted by a fluid (liquid or gas) per unit area. This is commonly expressed in units such as Pascals, atmospheres, or millimeters of mercury. Instruments like manometers and barometers are used to measure pressure in various applications, from weather forecasting to industrial processes. Accurate pressure measurements are crucial in many fields, including engineering, meteorology, and medicine. For instance, in healthcare, blood pressure is measured to assess cardiovascular health, while in aerospace, pressure readings help ensure the safety and performance of aircraft.
