## How to Convert Pounds per Square Foot to Atmospheres

To convert a measurement in pounds per square foot to a measurement in atmospheres, multiply the pressure by the following conversion ratio: 0.000473 atmospheres/pound per square foot.

Since one pound per square foot is equal to 0.000473 atmospheres, you can use this simple formula to convert:

atmospheres = pounds per square foot × 0.000473

The pressure in atmospheres is equal to the pressure in pounds per square foot multiplied by 0.000473.

For example, here's how to convert 5,000 pounds per square foot to atmospheres using the formula above.
atmospheres = (5,000 psf × 0.000473) = 2.362705 atm

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

## What Are 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 lbf / ft2

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

## What is an Atmosphere?

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.
