1. What is the Round Pool Volume Formula?

The formula calculates the volume of a circular swimming pool in gallons. It accounts for the pool's circular shape, depth, and converts cubic feet to gallons (1 cubic foot = 7.48 gallons).

2. How Does the Calculator Work?

The calculator uses the round pool volume formula:

\[ V = \pi \times R^2 \times D \times 7.48 \]

Where:

\( V \) — Volume in gallons
\( R \) — Radius of the pool in feet
\( D \) — Average depth of the pool in feet
7.48 — Conversion factor (gallons per cubic foot)

Explanation: The formula calculates the cylindrical volume (πR²D) then converts it from cubic feet to gallons.

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 the pool's radius (half of diameter) and average depth (shallow end + deep end ÷ 2). Enter values in feet.

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 two. For uniform depth pools, just use that depth.

Q2: What if my pool isn't perfectly round?
A: This calculator works best for truly circular pools. For oval pools, use an oval pool calculator instead.

Q3: Why convert to gallons?
A: Most pool chemicals and equipment specifications use gallons as the standard measurement unit.

Q4: How accurate is this calculation?
A: It's very accurate for perfectly round pools with uniform or gradually sloping bottoms.

Q5: Can I use meters instead of feet?
A: This calculator uses feet. For meters, you'd need to adjust the conversion factor (1 cubic meter = 264.172 gallons).
