## 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

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

## Units of Pressure Measurement

Units of pressure include pascals, hectopascals, atmospheres, bars, millibars, kilograms per square centimeter, kilograms per square meter, pounds per square inch, pounds per square foot, and torr.
