Round Pool Volume Calculator Gallons

Round 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 a round swimming pool based on its radius and depth.

Purpose: It helps pool owners and 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 is crucial for proper chemical treatment, pump sizing, and heating calculations.

Tips: Measure the pool's radius (half of diameter) and average depth. For sloping bottoms, use the average of shallow and deep ends.

Q1: How do I measure pool radius?
A: Measure the diameter (widest point across the pool) and divide by 2.

Q2: What if my pool has varying depths?
A: Use the average depth (shallow end depth + deep end depth divided by 2).

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

Q4: Does this work for oval pools?
A: No, this calculator is specifically for perfectly round pools.

Q5: How accurate is this calculation?
A: It's very accurate for perfect cylinders, but real pools may have slight variations.
