Circle Pool Volume Calculator Gallons

Pool Volume Formula:

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

Pool Volume:

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

Purpose: It helps pool owners and maintenance professionals determine water volume for chemical treatment, filling, and equipment sizing.

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 heating efficiency.

Tips: Measure the pool's radius from center to edge, and calculate average depth if the pool has a slope (shallow end + deep end ÷ 2).

Q1: How do I measure radius if I only know diameter?
A: Divide the diameter by 2 to get radius.

Q2: What if my pool has variable depth?
A: Use the average depth (shallow end + deep end) ÷ 2.

Q3: Why multiply by 7.48?
A: 1 cubic foot equals 7.48 gallons - this converts volume units.

Q4: How accurate is this calculation?
A: It's accurate for perfect cylinders. For irregular shapes, consider a professional assessment.

Q5: Can I use meters instead of feet?
A: No, this calculator uses feet. Convert meters to feet (1m = 3.28084ft) before calculating.
