Volume (gallons) vs Pool Length
Formula
## How to Calculate Pool Volume For a rectangular pool, multiply length x width x average depth to get cubic feet, then convert to gallons. ### Formula **Volume (cu ft) = Length x Width x Average Depth** **Gallons = Cubic Feet x 7.481** For variable-depth pools, average the shallow and deep end depths.
Exemplo Resolvido
A 30 ft x 15 ft pool with 5 ft average depth.
- 01Volume = 30 x 15 x 5 = 2,250 cubic feet
- 02Gallons = 2,250 x 7.481 = 16,832 gallons
- 03Liters = 2,250 x 28.317 = 63,713 liters
Perguntas Frequentes
Why do I need to know pool volume?
Pool volume is essential for properly dosing chemicals (chlorine, pH adjusters), calculating fill/drain time, and estimating water costs.
How do I find average depth?
Add the shallow end depth and deep end depth, then divide by 2. For example, (3 ft + 7 ft) / 2 = 5 ft average.
How much does it cost to fill a pool?
At $4 per 1,000 gallons (typical municipal rate), a 15,000-gallon pool costs about $60 to fill from a hose.
