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 of 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 (number of gallons in one cubic foot).

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 length and width at the longest points. For depth, average the shallow and deep end measurements if your pool has a slope.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure average depth?
A: For pools with varying depth, add the shallow end and deep end depths together and divide by two.

Q2: What if my pool isn't rectangular?
A: This calculator is for rectangular pools. For circular pools, use π × radius² × depth × 7.48.

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

Q4: How accurate is this calculation?
A: It provides a good estimate for standard rectangular pools. Irregular shapes may require more complex calculations.

Q5: Can I use meters instead of feet?
A: For metric measurements, use length × width × depth × 1000 (for liters) with measurements in meters.
