What is the S.I unit of pressure?

Pressure is a physical quantity that represents the force applied perpendicular to the surface of an object per unit area. Mathematically, it is expressed as:

Pressure = Force / Area

The SI unit of pressure is called the Pascal, symbolized as Pa. One Pascal is equivalent to one Newton per square meter (N/m²). This means that when a force of one Newton is applied uniformly over an area of one square meter, the resulting pressure is one Pascal.

The SI unit of pressure, Pascal, is named in honor of Blaise Pascal, a French mathematician, physicist, and inventor who contributed significantly to the study of pressure and fluid mechanics.

The concept of pressure and its measurement is widely used in various fields such as physics, engineering, meteorology, and medicine. For instance, atmospheric pressure, which is the pressure exerted by the weight of the atmosphere, is also measured in Pascals.

In summary, the SI unit of pressure is Pascal (Pa), and it is defined as one Newton of force acting on one square meter of area. This unit helps standardize the measurement of pressure across different disciplines and applications.
