## How to Convert Atmospheres to Pounds Per Square Inch

To convert an 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:

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.

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 lbfin^{2}

Pressure in pounds per square inch are equal to the pound-force divided by the area in square inches.
