PSI Full Form – What Does PSI Stand For?

The short answer is that the full form of PSI or PSI stands for “Pound per Square Inch”.

In detail, the full form of PSI or PSI stands for Pound per Square Inch. One PSI is equal to the pressure which is exerted when one pound-force is applied to an area of one square inch.

It is a US customary and imperial unit of pressure. A pound per square inch is sometimes also referred to as a pound-force per square inch. 1 pound per square inch can be written as 1 psi.

PSI can be expressed using the formula:

1 psi = 1 * (lbf)/(in)2

Pressure in pounds per square inch is equal to the pound-force divided by the area in square inches. So, PSI is the measurement of the force that applies to one square inch area.

Uses Of PSI

It is used to measure pressure in industrial and technical fields where gauge pressure measurements are needed. Pounds per square inch also used for things as simple as measuring tire pressure.

How to calculate pounds per square inch or PSI?

Pounds per square inch (PSI) is calculated from taking the total pound-force and dividing it by the area in inches squared.

How to Convert Pounds Per Square Inch to Pounds Per Square Foot?

To convert a pound per square inch measurement to a pound per square foot measurement, multiply the pressure by the conversion ratio. One pound per square inch is equal to 144 pounds per square foot, so use this simple formula to convert: pounds per square foot = pounds per square inch × 144

The pressure in pounds per square foot is equal to the pounds per square inch multiplied by 144.

For Example:

How to convert 5 pounds per square inch to pounds per square foot?

Byusing the formula above

5 psi = (5 × 144) = 720 psf
