1. What is the Pool Volume Formula?

The pool volume formula calculates the water capacity in gallons for rectangular pools. It multiplies length, width, and average depth (in feet) by 7.48 (the number of gallons in a cubic foot).

2. How Does the Calculator Work?

The calculator uses the pool volume formula:

Where:

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

Explanation: The formula 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 heating calculations.

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 depth for a sloping pool?
A: Add the shallow end depth and deep end depth, then divide by 2 to get average depth.

Q2: Does this work for non-rectangular pools?
A: This formula is for rectangular pools. Circular pools use π × radius² × depth × 7.48.

Q3: Why is 7.48 used in the formula?
A: There are 7.48 gallons in one cubic foot of water.

Q4: How accurate is this calculation?
A: Very accurate for rectangular pools with precise measurements. Irregular shapes require more complex calculations.

Q5: Can I use meters instead of feet?
A: Yes, but you would need to use a different conversion factor (1000 liters per cubic meter).
