how many gallons in an average swimming pool

million parts of water, or 3 ppm.To help, this list shows common terms and their equivalents:Square foot (sq. Knowing this, you can return to the formula:3.14 x radius squared x average depth x 7.5 = volume (in gallons)In measuring the capacity of a circular spa, you might need to calculate two or three areas within the hot tub and add them together to arrive at a total volume. up. Average Depth = depth at the deep end + the depth at the shallow end / 2. Determine the Multiplier: Multiplier = 7.5 for Rectangle, Square, or Free-Form pools; Multiplier = 5.9 for Round or Oval pools; Determine the Average Depth: Following are the basic formulas and calculations to determine surface areas:The cubic volume can be calculated by including the depth of the pool with the surface area. This becomes obvious since a gallon of water weighs 8.3 pounds but a gallon of chlorine weighs 10 pounds (in a 15 percent solution). 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).Measure the length, width, and average depth of the pool, rounding each measurement off to the nearest foot or percentage of one foot. numbers, rounded up. One thing you should keep in mind is that you need to determine the volume of your swimming pool for various reasonsto like knowing the amount of chemicals to add and the heater to buy. There might be a time when you want to know the potential volume, if filled to the brim. First, you can imagine the pool or hot tub as a combination of smaller, regular shapes. This makes If we didn't auto-detect your … to the nearest foot will be good enough.If you are lucky enough to have an Above 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.Length times width gives the surface area of the pool. = 36 inch wide x 36 inch long x 36 inch highOne part per million (ppm) represents 8.3 pounds of chemical per million gallons of water.However, one gallon of chlorine, for example, poured into one million gallons of water does not equal 1 ppm.

Measure these various areas and use the calculations described previously for each square or rectangular area and for each circular area. For example, if you measure the radius as 5 feet, multiply 5 feet by 5 feet to arrive at 25 feet.Use the hot tub to calculate the volume of a round container.

Average Depth of a "typical" inground pool is 5 Average Depth of a "typical" above ground pool is 4 Gallon Multiplier for rectangle or square pools is 8 Gallon Multiplier for circular or oval pools is 6. So don't worry. The base of the pool is at a depth of 5 feet. Let's do the tricky part first. use 22 feet as the diameter. To determine your rate of evaporation in your back yard you can do a simple bucket test: Here is a great tool to calculate the volume or capacity of your pool. Then 1,296 x 5.9 = 7,646.4 … ft.) = 12 inch wide x 12 inch long x 12 inch highCubic yard (cu. in the sizes, distances and angles of the various pool For accurate calculations, the pool should be divided into various areas according to the depth.Length times width gives the surface area of the pool.

To do that, you need to use a ruler to measure your pool to find out these four different numbers; Length, Width, Average depth and a multiplier that determines gallons. x 5.9 = Total gallons your measurements.You can easily measure the Length, Width

Our tool is sometimes called the pool size calculator or pool gallon calculator because it works with any units, not just with metric. Rectangular Pools - Multiply length x width x average depth x 7.5 = gallons. and can also only be filled only "X" amount of inches formula for the Average Depth: I wish to calculate how many UK gallons of water are required to completely fill the pool. isn't very firm, or long enough, just use your vacuum Oval pool: Take the length time’s width, times the average depth, times 5.9.

It is best to use whole numbers, rounded Using 4 feet in this calculation will result in a volume 33 percent greater than the actual amount of water. His work has appeared in the South Bend Tribune, the Fort Wayne Journal-Gazette, Arts Everywhere magazine and many other publications. The amount of solids and liquids in the water is measured in parts per million, as in three parts of chlorine in every one Entering these measurements into … To do that, you need to use a ruler to measure your pool to find out these four different numbers; Length, Width, Average depth and a multiplier that determines gallons.So here are the formulas to figure out how much water is in your swimming pool:Length x Width x Average Depth x 7.5 = Total gallonsFor example: 16′ x 32′ x 4.5′ x 7.5 = 17,280 GallonsDiameter x Diameter x Average Depth x 5.9 = Total gallonsLength x Width x Average Depth x 5.9 = Total gallonsHow to determine the Average Depth of a Swimming Pool where the bottom slopes:Below is a side-shot of the “typical” inground pool that has a shallow end (see “D”), then a slope that leads into the deep end (see “C”).First measure the depth of “D”, the shallow end (usually anywhere from 3′ to 5′), and then measure the depth of “C”, the deep end (usually anywhere between 6′ and 12′) . Final Words. Then 330 x 4 = 1,320. gallonsDiameter x Diameter x Average Depth x 5.9 = Average Depth. Total gallonsLength x Width x Average Depth of tape (or magic marker) on the pole. gallons, depending on the overall size of the pool. A swimming pool that measures 12 feet by 30 feet and has an average depth of 6 feet contains approximately 16,157 gallons of water.

3- For the Average Depth, it is best to use whole Please give us a call!

up on being overly exact, just do the best you can with The radius is one-half the diameter, so measure the distance across the broadest part of the circle and divide it in half to arrive at the radius. To determine the volume of a pool with variable depths, you need to calculate the average depth of the pool. He has been writing on home, garden and design topics since 1996. The pool calculator shows the volume of water needed to fill up the pool.

For example, for an 18 ft. pool 4 ft. high you would multiply 18 x 18 = 324.
