Above Ground Pool Volume Calculator

Pool Volume Formula:

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

Pool Volume: gallons

Definition: This calculator estimates the water volume in gallons for circular above-ground pools based on radius and depth.

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

The calculator uses the formula:

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

Where:

Explanation: The formula calculates the cylindrical volume in cubic feet then converts it to gallons.

Details: Accurate volume measurement ensures proper chemical dosing, pump sizing, and water replacement calculations.

Tips: Measure the pool's radius from center to edge and average depth (for sloped bottoms). All values must be > 0.

Q1: How do I measure pool radius?
A: Measure from the center of the pool to the edge, 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 average radius measurements.

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

Q4: How do I account for a sloped bottom?
A: Use the average depth (shallow end + deep end ÷ 2).

Q5: Does this include the water in the filtration system?
A: No, add approximately 50-100 gallons for typical above-ground pool systems.
