1. What is the Round Pool Volume Formula?

The round pool volume formula calculates the water capacity in gallons for circular swimming pools. It accounts for the pool's radius and average depth to determine total volume.

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 cubic feet 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, heating calculations, and water replacement planning.

4. Using the Calculator

Tips: Measure the pool's radius from center to edge in feet. For depth, average the shallow and deep end measurements if applicable. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure pool radius if I only know diameter?
A: Simply divide the diameter by 2 to get the radius.

Q2: What if my pool has variable depth?
A: Calculate average depth by adding the shallow end and deep end depths, then dividing by 2.

Q3: Why multiply by 7.48?
A: There are 7.48 gallons in one cubic foot of water - this converts volume from cubic feet to gallons.

Q4: How accurate is this calculation?
A: Very accurate for perfectly round pools with straight sides. For freeform pools, consider breaking into multiple circular sections.

Q5: Can I use meters instead of feet?
A: Yes, but you'll need to use a different conversion factor (1 cubic meter = 264.172 gallons).
