How to Convert Atmospheres to Pounds per Square Inch
To convert atmospheres to pounds per square inch, multiply the pressure by the following conversion ratio: 14.695964 pounds per square inch/atmosphere.
Since one atmosphere is equal to 14.695964 pounds per square inch, you can use this simple formula to convert:
pounds per square inch = atmospheres × 14.695964
The pressure in pounds per square inch is equal to the pressure in atmospheres multiplied by 14.695964.
For example, here's how to convert 5 atmospheres to pounds per square inch using the formula above.
pounds per square inch = (5 atm × 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.
What Is an Atmosphere?
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.

What Are 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 lbf / in2
Pressure in pounds per square inch are equal to the pound-force divided by the area in square inches.
