1. What is an Above Ground Pool Calculator Gallons?

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

Purpose: It helps pool owners and professionals determine the correct amount of water needed to fill a pool or calculate chemical treatments.

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 in gallons
\( r \) — Pool radius (feet)
\( D \) — Average 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 calculation is essential for proper chemical treatment, pump sizing, and heating requirements.

4. Using the Calculator

Tips: Measure the pool's radius (half of diameter) and average depth (measure shallow and deep ends if applicable). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure pool radius?
A: Measure the distance from the center to the edge of the pool, or divide the diameter by 2.

Q2: What if my pool isn't perfectly circular?
A: This calculator is for circular pools. For oval pools, use an average radius or a different formula.

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

Q4: Should I include the pool wall height?
A: No, only include the water depth, not the total wall height.

Q5: How accurate is this calculation?
A: It's very accurate for standard circular pools. For irregular shapes, consider professional measurement.
