What is the measurement unit of pressure?

The measurement unit of pressure is Pascals. Pressure is defined as the force applied per unit area. The Pascal (symbol: Pa) quantifies the amount of force, measured in Newtons, that is applied over an area, measured in square meters. Specifically, 1 Pascal is equivalent to 1 Newton of force exerted over an area of 1 square meter. This unit is widely used in science and engineering contexts to provide a clear and consistent measure of pressure in various applications, such as meteorology, hydraulics, and physics experiments.

While Newtons are a unit of force and Joules measure energy, they do not directly express pressure. Barometers, on the other hand, are instruments used to measure atmospheric pressure, but they do not serve as a unit of measurement themselves. Thus, Pascals is the correct and standard unit for pressure measurement.
