How to Convert Pounds Per Square Inch to Atmospheres

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

To convert a pound per square inch measurement to a atmosphere measurement, multiply the pressure by the conversion ratio. One pound per square inch is equal to 0.068046 atmospheres, so use this simple formula to convert:

atmospheres = pounds per square inch × 0.068046

The pressure in atmospheres is equal to the pounds per square inch multiplied by 0.068046.

For example, here's how to convert 5 pounds per square inch to atmospheres using the formula above.
5 psi = (5 × 0.068046) = 0.340229 atm

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

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.

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.
