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 equation calculates cubic feet first (L×W×D) then converts to gallons by multiplying by 7.48.

3. Importance of Pool Volume Calculation

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

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How do I measure average depth?
A: For pools with varying depths: (shallow end depth + deep end depth) ÷ 2.

Q2: What about irregular shaped pools?
A: Break into rectangular sections, calculate each separately, then sum the volumes.

Q3: Why 7.48 as the conversion factor?
A: There are 7.48052 gallons in one cubic foot of water (rounded to 7.48 for simplicity).

Q4: How accurate is this calculation?
A: Very accurate for rectangular pools. For other shapes, consider specialized formulas.

Q5: Can I use meters instead of feet?
A: For metric measurements, use different conversion factors (1 m³ = 264.172 gallons).
