Editing Psi (section)

=== Psi in Air Pressure ===
In a scientific context, '''Psi''' (pounds per square inch) is a unit of pressure used to quantify the amount of force exerted on a given area. This measurement is crucial in various fields, including meteorology, engineering, and fluid dynamics. 

<math>P = \frac{F}{A}</math>

where:
* <math>P</math> is the pressure (measured in Psi),
* <math>F</math> is the force applied,
* <math>A</math> is the area over which the force is distributed.

Psi as air pressure is fundamental to understanding how pressure waves propagate, which is directly related to sound, vibration, and various other physical phenomena.
