1. What is the Pool Volume Formula?

The pool volume formula calculates the total gallons of water in a rectangular pool by multiplying length, width, average depth, and the conversion factor 7.48 (gallons per cubic foot).

2. How Does the Calculator Work?

The calculator uses the pool volume equation:

Where:

• \( V \) — Volume in gallons
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( D \) — Average depth in feet
• 7.48 — Conversion factor (gallons per cubic foot)

Explanation: The formula calculates cubic feet first (L×W×D) then converts to gallons by multiplying by 7.48 (since 1 cubic foot = 7.48 gallons).

3. Importance of Pool Volume Calculation

Details: Knowing your pool's volume is essential for proper chemical treatment, pump sizing, heater selection, and general maintenance.

4. Using the Calculator

Tips: Measure pool dimensions accurately. For depth, average shallow and deep ends if applicable. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure average depth?
A: Add the shallow end depth to the deep end depth, then divide by 2. For uniform depth pools, just use that measurement.

Q2: What about irregular shaped pools?
A: For circular pools, use π×r²×D×7.48. For complex shapes, break into rectangular sections and calculate each separately.

Q3: Why is volume important for pool maintenance?
A: Chemical dosages are based on pool volume. Too little won't be effective, too much can damage equipment or irritate swimmers.

Q4: How accurate is this calculation?
A: Very accurate for rectangular pools with consistent slopes. Less accurate for freeform pools with varying depths.

Q5: What's the 7.48 conversion factor?
A: It converts cubic feet to gallons (1 cubic foot = 7.48052 US gallons).
