On quick note, 1 PSI = 144 PSF, use this PSI to PSF conversion tool that allows you to easily convert between these two pressure units.
PSI (Pounds per Square Inch) and PSF (Pounds per Square Foot) are both units used to measure pressure, but they differ in the area they represent. PSI measures the pressure exerted on a 1-square-inch area, while PSF measures the pressure exerted on a 1-square-foot area.
For example, let’s consider the following sample conversions:
- 1 PSI = 144 PSF – This means that a pressure of 1 pound per square inch is equivalent to 144 pounds per square foot.
- 10 PSI = 1,440 PSF – In this case, a pressure of 10 pounds per square inch is equivalent to 1,440 pounds per square foot.
- 50 PSI = 7,200 PSF – A pressure of 50 pounds per square inch is equal to 7,200 pounds per square foot.

| 25 psi to psf | 3,600 | PSF = PSI × 144 |
| 30 psi to psf | 4,320 | PSF = PSI × 144 |
| 100 psi to psf | 14,400 | PSF = PSI × 144 |
| 250 psi to psf | 36,000 | PSF = PSI × 144 |
| 1,000 psi to psf | 144,000 | PSF = PSI × 144 |
| 1,500 psi to psf | 216,000 | PSF = PSI × 144 |
| 2,000 psi to psf | 288,000 | PSF = PSI × 144 |
The conversion equation used in the table is:
PSF = PSI × 144
Where:
- PSF is the pressure in pounds per square foot
- PSI is the pressure in pounds per square inch
This equation is used to convert the given PSI values to their corresponding PSF values.
PSI to PSF Conversion Formula
The formula to convert PSI to PSF is:
PSF = PSI × 144
Let’s walk through a few examples using this formula:
- Example 1: Converting 5 PSI to PSF
- PSF = PSI × 144
- PSF = 5 × 144
- PSF = 720
- Therefore, 5 PSI is equivalent to 720 PSF.
- Example 2: Converting 20 PSI to PSF
- PSF = PSI × 144
- PSF = 20 × 144
- PSF = 2,880
- Therefore, 20 PSI is equivalent to 2,880 PSF.
- Example 3: Converting 100 PSI to PSF
- PSF = PSI × 144
- PSF = 100 × 144
- PSF = 14,400
- Therefore, 100 PSI is equivalent to 14,400 PSF.
The key thing to remember is that the conversion factor between PSI and PSF is always 144.
This is because there are 144 square inches in a square foot (12 inches × 12 inches = 144 square inches).

Is PSF the Same as PSI?
No, PSF (Pounds per Square Foot) and PSI (Pounds per Square Inch) are not the same. They are both units used to measure pressure, but they differ in the area they represent.
PSI measures the pressure exerted on a 1-square-inch area, while PSF measures the pressure exerted on a 1-square-foot area.
This means that the values for the same amount of pressure can differ significantly depending on whether you’re using PSI or PSF.
For example, a pressure of 10 PSI is equivalent to 1,440 PSF (10 PSI × 144 = 1,440 PSF). This highlights the importance of using the correct pressure unit when working on various projects or calculations.
How Do You Calculate Pressure in PSF?
To calculate pressure in pounds per square foot (PSF), you can use the following formula:
PSF = Force / Area
Where:
- PSF is the pressure in pounds per square foot
- Force is the force applied (in pounds)
- Area is the surface area (in square feet)
Suppose you have a force of 1,000 pounds being applied to a surface with an area of 50 square feet. To calculate the pressure in PSF, you would use the following steps:
- Identify the given values:
- Force = 1,000 pounds
- Area = 50 square feet
- Apply the formula:
- PSF = Force / Area
- PSF = 1,000 pounds / 50 square feet
- PSF = 20 pounds per square foot
The pressure exerted on the 50-square-foot surface with a force of 1,000 pounds is 20 PSF.
What is a PSF Equal To?
PSF (Pounds per Square Foot) is a unit of pressure that is equal to the force of 1 pound applied evenly over an area of 1 square foot.
Specifically, 1 PSF is equivalent to:
- 1 pound of force per square foot
- 4.88 kilograms per square meter (kg/m²)
- 0.048 kilonewtons per square meter (kN/m²)
The conversion factors are as follows:
- 1 PSF = 1 pound per square foot
- 1 PSF = 4.88 kg/m²
- 1 PSF = 0.048 kN/m²
These conversion factors allow you to easily convert between PSF and other pressure units, such as kilograms per square meter (kg/m²) or kilonewtons per square meter (kN/m²), depending on the requirements of your application.
How Much is 2160 PSF in PSI?
To convert 2160 pounds per square foot (PSF) to pounds per square inch (PSI), we can use the following formula:
PSI = PSF / 144
Where:
- PSI is the pressure in pounds per square inch
- PSF is the pressure in pounds per square foot
Plugging in the values:
- PSI = 2160 PSF / 144
- PSI = 15 PSI
2160 pounds per square foot (PSF) is equivalent to 15 pounds per square inch (PSI).
The reason for dividing by 144 is that there are 144 square inches in a square foot (12 inches × 12 inches = 144 square inches).
This conversion factor allows us to convert the pressure from a 1-square-foot area to a 1-square-inch area.
