Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool (expressed in gallons).
Rectangular Pools - Multiply length x width x average depth x 7.5 = gallons. Round Pools- Multiply diameter x diameter x average depth x 5.9 = gallons. Oval Pools - Multiply full width x full length x average depth x 6.7 = gallons. * Irregular shapes and size pools capacity should be determined by your pool builder or specialist. * If your pool has sloping sides, multiply your final figure of gallonage by 0.85 for correct gallonage.
