Round Pools / multiplier = 5.9


Diameter x Diameter x Average Depth of water (Ft.) x 5.9 = Total Gallons (US)
IE: 24' Round Pool / 48" deep sidewall / 42" (3.5 ft.) Water depth 24 x 24 = 576 x 3.5' = 2016 x 5.9 = 11,894 gallons
*Depth of Water in Feet (Ft.) = Subtract sidewall depth by 6" (See Below ** for pools with shallow & deep ends)


Oval Pools / multiplier = 5.9


Length of pool x Width of pool x Average Depth of water (Ft.) x 5.9 = Total Gallons (US)
IE: 17' x 35' Oval Pool / 54" deep sidewall / 48" (4 ft.) Water depth 17 x 35 = 595 x 4' = 2380 x 5.9 = 14, 042 gallons
*Depth of Water in Feet (Ft.) = Subtract sidewall depth by 6" for (for onedepth pools & Above Grounds) Or... **Determine Average Depth: Measure the Shallow end and the Deep end depth. Add them together and divide by 2. Example: Shallow end (2') + deep end (6') = 8' / 8' divided by 2 = Average Depth of 4'


Rectangular Pools / Square or Free Form / multiplier = 7.5


Length of pool x width of pool x Average depth of water* (Ft.) x 7.5 = Total gallons (US)
IE: 16' x 32' Rectangular Pool / 42" deep sidewall / 60" (5 ft.) Average Water depth 16 x 32 = 512 x 5' = 2560 x 7.5 = 19,200 gallons
**Determine Average Depth = Measure the Shallow end and the Deep end depth. Add them together and divide by two (2). Example: shallow end (2 1/2') + deep end (7 1/2') = 10' / 10' divided by 2 = Average Depth of 5'
