How to Convert Pounds per Square Foot to Kilopascals
To convert a measurement in pounds per square foot to a measurement in kilopascals, multiply the pressure by the following conversion ratio: 0.04788 kilopascals/pound per square foot.
Since one pound per square foot is equal to 0.04788 kilopascals, you can use this simple formula to convert:
kilopascals = pounds per square foot × 0.04788
The pressure in kilopascals is equal to the pressure in pounds per square foot multiplied by 0.04788.
For example, here's how to convert 5 pounds per square foot to kilopascals using the formula above.
kilopascals = (5 psf × 0.04788) = 0.239401 kPa
Pounds per square foot and kilopascals 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 a Kilopascal?
The kilopascal is a multiple of the pascal, which is the SI derived unit for pressure. In the metric system, "kilo" is the prefix for thousands, or 103. Kilopascals can be abbreviated as kPa; for example, 1 kilopascal can be written as 1 kPa.
