1. What is an Above Ground Swimming Pool Volume Calculator?

Definition: This calculator estimates the water volume in gallons for circular above-ground swimming pools based on their dimensions.

Purpose: It helps pool owners and maintenance professionals determine the correct amount of water needed for filling or chemical treatment.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{gal} = \pi \times r^2 \times D \times 7.48 \]

Where:

\( V_{gal} \) — Volume of water (gallons)
\( r \) — Pool radius (feet)
\( D \) — Pool depth (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: Accurate volume measurement is crucial for proper chemical treatment, pump sizing, and water replacement calculations.

4. Using the Calculator

Tips: Measure the pool's radius (half of diameter) and average depth. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure pool depth accurately?
A: Take measurements at several points (shallow end, deep end, middle) and use the average.

Q2: What if my pool isn't perfectly circular?
A: This calculator assumes perfect circular shape. For oval pools, use length × width × depth × 5.9.

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

Q4: Does this work for irregular shaped pools?
A: No, this is only for circular pools. For irregular shapes, consult a pool professional.

Q5: How often should I recalculate volume?
A: Recalculate if you change the water level significantly or modify the pool structure.
