๐ก How to Calculate Pool Volume
Pool volume is calculated using the pool's surface area multiplied by the average depth, then converted to gallons. For rectangular pools: Length ร Width ร Average Depth ร 7.48 gallons/cu ft. For round pools: ฯ ร radiusยฒ ร Average Depth ร 7.48. Average depth = (shallow end + deep end) รท 2.
Knowing your pool volume is essential for proper chemical dosing, heater sizing, pump selection, and filling time estimation. A garden hose delivers approximately 5โ10 gallons per minute, so a 15,000-gallon pool takes 25โ50 hours to fill from empty.
A 30ร15 ft rectangular pool with 3 ft shallow and 8 ft deep end: average depth = 5.5 ft. Volume = 30 ร 15 ร 5.5 = 2,475 cu ft ร 7.48 = 18,512 gallons (70,083 liters).
