1. What is a PSI to PSF Calculator?

Definition: This calculator converts pressure from pounds per square inch (PSI) to pounds per square foot (PSF).

Purpose: It helps engineers, architects, and construction professionals convert between these common pressure units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( PSF \) — Pressure in pounds per square foot
• \( PSI \) — Pressure in pounds per square inch
• \( 144 \) — Conversion factor (12 in/ft × 12 in/ft)

Explanation: Since 1 foot = 12 inches, 1 square foot = 144 square inches (12 × 12).

3. Importance of PSI to PSF Conversion

Details: Different applications use different units - structural calculations often use PSF while fluid systems use PSI.

4. Using the Calculator

Tips: Simply enter the PSI value and the calculator will instantly provide the equivalent PSF value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 144?
A: Because there are 144 square inches in one square foot (12 inches × 12 inches).

Q2: When would I need to convert PSI to PSF?
A: Common in structural engineering when converting fluid pressures to load distributions on surfaces.

Q3: Is this conversion exact?
A: Yes, it's a mathematical conversion with no approximation.

Q4: Can I convert PSF back to PSI?
A: Yes, by dividing PSF by 144 (PSI = PSF / 144).

Q5: What's a typical PSI value in construction?
A: Concrete strength is often measured in PSI (e.g., 3000 PSI concrete), while floor loads are in PSF.
