PSI to PSF Calculator

Formula

The formula to calculate PSF from PSI is:

\[ \text{PSF} = \text{PSI} \times 144 \]

Where:

(PSF) is pounds per square foot (lbs/ft²)
(PSI) is pounds per square inch (lbs/in²)

What is PSF?

Pounds per square foot (PSF) is a unit of pressure that describes the amount of force exerted over a square foot area. It is commonly used in engineering and construction to measure loads and stresses on surfaces.

Example Calculation

Let's assume the following value:

Pounds per Square Inch (PSI) = 10 lbs/in²

Using the formula:

\[ \text{PSF} = 10 \times 144 = 1440 \]

The pounds per square foot (PSF) is 1440 lbs/ft².
