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.
