How to Convert Atmospheres to Pounds Per Square Foot

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

To convert an atmosphere measurement to a pound per square foot measurement, multiply the pressure by the conversion ratio.

Since one atmosphere is equal to 2,116.218862 pounds per square foot, you can use this simple formula to convert:

pounds per square foot = atmospheres × 2,116.218862

The pressure in pounds per square foot is equal to the atmospheres multiplied by 2,116.218862.

For example, here's how to convert 5 atmospheres to pounds per square foot using the formula above.
5 atm = (5 × 2,116.218862) = 10,581.094311 psf

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


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 Foot

One pound per square foot is the pressure of equal to one pound-force per square foot.

The pound per square foot is a US customary and imperial unit of pressure. Pounds per square foot can be abbreviated as psf; for example, 1 pound per square foot can be written as 1 psf.

PSF can be expressed using the formula:
1 psf = 1 lbfft2

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