Pound Per Square Inch Definition and Usage
One pound per square inch is the pressure of equal to one pound-force per square inch.
The pound per square inch 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. Pounds per square inch can be abbreviated as psi; for example, 1 pound per square inch can be written as 1 psi.
PSI can be expressed using the formula:
1 psi = 1 lbfin2
Pressure in pounds per square inch are equal to the pound-force divided by the area in square inches.
