Pool Volume Calculator
Calculate the volume of water in your swimming pool. Enter your pool dimensions to find the total volume. Essential for proper chemical dosing, heating costs, and water bills. Works for rectangular, round, and oval shaped pools.
How We Calculate This
Rectangular: L × W × D × 7.48 gallons. Round: π × r² × D × 7.48 gallons. Oval: L × W × D × 5.9 gallons (0.785 × 7.48). All measurements in feet.
Frequently Asked Questions
How do I calculate average pool depth?
Add the shallow end depth to the deep end depth and divide by 2. For example, if shallow is 3 ft and deep is 8 ft: (3 + 8) ÷ 2 = 5.5 ft average depth.
How many gallons per cubic foot?
There are 7.48 gallons per cubic foot of water. Volume in gallons = cubic feet × 7.48.
How long does it take to fill a pool?
A standard garden hose delivers about 9 gallons per minute (540 GPH). A 20,000 gallon pool takes about 37 hours to fill. Larger supply lines can fill faster.
How much does it cost to fill a pool?
Water costs about $0.002-0.006 per gallon in most areas. A 20,000 gallon pool costs $40-120 to fill. Check your local water rates for accurate estimates.
