1. What is the Round Pool Volume Formula?

The round pool volume formula calculates the total gallons of water needed to fill a circular swimming pool. It accounts for the pool's radius, average depth, and converts cubic feet to gallons.

2. How Does the Calculator Work?

The calculator uses the formula:

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 in cubic feet and converts it 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 diameter and divide by 2 to get radius. For depth, average the shallow and deep end measurements if applicable.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my pool's average depth?
A: For pools with a slope, measure the shallowest and deepest points and calculate the average.

Q2: What if my pool isn't perfectly round?
A: This calculation works best for true circular pools. For oval pools, use a different formula.

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

Q4: How accurate is this calculation?
A: It's accurate for perfectly round pools with uniform depth. Irregular shapes require more complex calculations.

Q5: Can I use meters instead of feet?
A: You would need to use a different conversion factor (1 cubic meter = 264.172 gallons).
