Swimming Pool Volume Calculator

Swimming pool volume depends on the shape of the pool.

Rectangular pool: Volume = Length × Width × Average Depth

Circular pool: Volume = π × Radius² × Average Depth

Oval pool: Volume = π × (Length/2) × (Width/2) × Average Depth

Unit conversions:

• Cubic feet × 7.48 = Gallons
• Cubic meters × 1,000 = Liters
• 1 gallon = 3.785 liters
• 1 cubic foot = 0.0283 cubic meters

Typical pool volumes:

• Small residential (12×24 ft, 5 ft avg depth): ~10,800 gallons
• Medium residential (16×32 ft, 5.5 ft avg depth): ~21,000 gallons
• Large residential (20×40 ft, 6 ft avg depth): ~36,000 gallons
• Olympic pool (50×25 m, 2 m depth): ~660,000 gallons

Practical uses:

• Chemical dosing (chlorine, pH adjusters)
• Heating cost estimates
• Fill time calculation
• Water bill estimates
