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 × 7.48 (the number of gallons in one cubic foot of water).

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 maintenance planning.

4. Using the Calculator

Tips: Measure length and width at their longest points. For depth, average the shallow and deep end measurements if your pool has varying depth.

5. Frequently Asked Questions (FAQ)

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

Q2: What if my pool isn't rectangular?
A: Different formulas exist for circular, oval, or kidney-shaped pools.

Q3: Why is accurate volume important?
A: Proper chemical dosing requires knowing exact volume to avoid under/over treatment.

Q4: How often should I recalculate volume?
A: Only needed if you significantly change pool dimensions or shape.

Q5: What's the margin of error?
A: Typically ±5% if measurements are accurate, more for irregular shapes.
