What Is Pressure?
Pressure is the force exerted on an object by something else. Pressure measurements are most often used in meteorology, marine, and industrial applications.
There are many different types of pressure, including fluid and liquid pressure, vapor and gas pressure, stagnation pressure, surface pressure, and negative pressure.
How to Calculate Pressure
Pressure is commonly measured in pascals or pounds per square inch, or PSI. Pressure is equal to the force F applied divided by the area A of the object.
Thus the formula to calculate pressure is:
p = F / A
You can learn more about how to apply this formula using our pressure calculator.
Static fluid pressure can also be found by multiplying fluid density ρ times height h, times gravity g.
Thus the formula to calculate static fluid pressure is:
P = ρgh
