Full bio

Pounds per square inch are a measurement of pressure.

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.

Uses

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

How Much Is a Pound per Square Inch?

How to Convert Pounds per Square Inch

To convert pounds per square inch to another unit of pressure, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for pounds per square inch in the conversion table below.

Then, multiply the pressure measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

pounds per square inch × conversion factor = result
