PSF = PSI × 144
| From: | To: |
PSI (pounds per square inch) and PSF (pounds per square foot) are both units of pressure measurement. The conversion between them is important in various engineering and construction applications where pressure needs to be expressed in different units.
The calculator uses the simple conversion formula:
Where:
Explanation: This conversion works because there are 144 square inches in one square foot, so pressure measured per square inch needs to be multiplied by 144 to get the equivalent pressure per square foot.
Details: Accurate pressure unit conversion is crucial in engineering, construction, and physics applications where different systems of measurement are used. Converting between PSI and PSF ensures consistency in calculations and specifications across different measurement standards.
Tips: Enter the pressure value in PSI (pounds per square inch). The value must be a non-negative number. The calculator will automatically compute and display the equivalent value in PSF (pounds per square foot).
Q1: Why is the conversion factor 144?
A: Because there are 12 inches in a foot, and area is squared, so 12 × 12 = 144 square inches in a square foot.
Q2: When would I need to convert PSI to PSF?
A: This conversion is commonly needed in structural engineering, construction, and physics when working with pressure distributions over different surface areas.
Q3: Are PSI and PSF used in specific industries?
A: Yes, PSI is more common in mechanical engineering and fluid systems, while PSF is often used in structural engineering and building design.
Q4: Can this calculator handle decimal inputs?
A: Yes, the calculator accepts decimal values for more precise conversions.
Q5: Is the conversion the same in both directions?
A: To convert from PSF to PSI, you would divide by 144 instead of multiplying.
