How many
gallons of water are in my pool?
In order to figure out the proper doses of
chemicals for your pool, you need to determine how many gallons of
water it holds. To do that, you need to know four different numbers.
Length, Width, Average depth and a multiplier that determines
gallons. Here are the formulas:
Rectangular, Square or Free
Form Pools:
Length x Width x Average Depth x 7.5 = Total
gallons
(IE: 16' x 32' x 4.5' x 7.5 = 18,201 Gallons)
Circular
Pools:
Diameter x Diameter x Average Depth x 5.9 =
Total gallons
(IE: 18' x 18' x 4' x 5.9 = 7,646 Gallons)
Oval
Pools:
Long Diameter x Short Diameter x Average Depth
x 5.9 = Total gallons
(IE: 15' x 30' x 4' x 5.9 = 9,293 Gallons)
To determine average depth in a
pool where the bottom slopes: Measure the shallow end and measure
the deep end. Add them together and divide by 2. This is the average
depth of your pool.
Below, we have created some handy charts of
the most popular sizes of pools and how many gallons of water are in
them.
