1. What is a Round Pool Volume Calculator?

Definition: This calculator estimates the volume of water in gallons for a round swimming pool based on its radius and depth.

Purpose: It helps pool owners and professionals determine the correct amount of water needed to fill a round pool.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{gal} \) — Volume in gallons
• \( r \) — Radius of the pool (feet)
• \( D \) — Depth of the pool (feet)
• 7.48 — Conversion factor (cubic feet to gallons)

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 radius (half of diameter) and average depth. For variable depth pools, use the average of shallow and deep ends.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: Very accurate for perfectly round pools with uniform depth. Real-world measurements may vary slightly.

Q2: What if my pool isn't perfectly round?
A: For oval pools, use an oval pool calculator. For freeform pools, break into sections and calculate separately.

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

Q4: Should I include the waterline tile area?
A: No, measure to the normal operating water level, not the very top of the pool wall.

Q5: How do I measure depth for a sloping pool?
A: Average the shallow end depth and deep end depth (e.g., (3ft + 8ft)/2 = 5.5ft).
