How to Convert Atmospheres to Pounds Per Square Inch

Calculators can be used to convert measurements from one unit to another

To convert a atmosphere measurement to a pound per square inch measurement, multiply the pressure by the conversion ratio. One atmosphere is equal to 14.695964 pounds per square inch, so use this simple formula to convert:

pounds per square inch = atmospheres × 14.695964

The pressure in pounds per square inch is equal to the atmospheres multiplied by 14.695964.

For example, here's how to convert 5 atmospheres to pounds per square inch using the formula above.
5 atm = (5 × 14.695964) = 73.479822 psi

Atmospheres and pounds per square inch are both units used to measure pressure. Keep reading to learn more about each unit of measure.

Atmospheres

The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.

Atmospheres can be abbreviated as atm, for example 1 atmosphere can be written as 1 atm.

Pounds Per Square Inch

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.
