1. What is PSI to Feet Conversion?

Definition: This calculator converts water pressure in pounds per square inch (PSI) to equivalent head height in feet.

Purpose: It helps hydraulic engineers, plumbers, and irrigation specialists understand pressure in terms of water column height.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( h \) — Head height (feet)
• \( P \) — Pressure (psi)
• 2.31 — Conversion factor (feet of water per psi)

Explanation: The conversion factor comes from the specific weight of water (1 psi = 2.31 feet of water head).

3. Importance of PSI to Feet Conversion

Details: Understanding pressure in terms of water height is essential for designing water systems, pumps, and understanding natural water pressure.

4. Using the Calculator

Tips: Simply enter the pressure value in PSI. The calculator will instantly show the equivalent head height in feet.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 2.31?
A: It's derived from the specific weight of water (1 psi = 2.31 feet of water column at standard conditions).

Q2: Does this work for other liquids?
A: No, this is specific to water. Other liquids would require different conversion factors based on their specific gravity.

Q3: Is temperature considered in this calculation?
A: The standard calculation assumes water at 60°F. For precise applications, temperature corrections may be needed.

Q4: How accurate is this conversion?
A: For most practical purposes, it's sufficiently accurate. The exact value is 2.30666 feet per psi.

Q5: What's the reverse calculation (feet to PSI)?
A: Divide feet by 2.31 or multiply by 0.433 (which is 1/2.31).
