**For example,**here's how to convert 5,000 pounds per square foot to atmospheres using the formula above.

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

## 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 lbfft^{2}

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

## 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.
