# What is the formula for the amount of gallons in a round 18ft diam x 48in depth swimming pool?

The formula for the volume of a cylinder is Volume = height * pi * radius squared. That gives the volume in cubic feet, cubic meters or whatever your unit of measure might be. Convert from cubic ft to gallons using: 1 cubic foot = 7.480 519 481 gallon [US, liquid]

### What is the formula for how much water goes in a pool?

Here is the formula for calculating gallons of water to fill a swimming pool Calculate Your Pool's Water Volume Overview: In order to figure out 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: the length, width, average depth, and a multiplier that determines gallons. Here is the formula: Length * Width * Average Depth *…

### How many gallons of water does it take to fill a swimming pool that is 5'x30'x4'?

The formula for figuring out the amount of gallons is on the back of pool chemical containers. I am not sure what the formula is for an oval. Check here: http://www.poolspa.com/calculator/ If the pool floor slopes uniformly from end to end, the average depth can be found by adding the deepest and shallowest depth measurements and dividing the results by two. If the pool's dimensions are in feet, the volume will be in cubic feet…

### How many gallons of water does it take to fill a 16X32 foot pool?

Here is the formula for calculating gallons of water to fill a swimming pool Calculate Your Pool's Water Volume Overview: In order to figure out 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: the length, width, average depth, and a multiplier that determines gallons. Here is the formula: Length * Width * Average Depth *…

### How do you measure water?

Water is usually measured by volume, that is, in liters or gallons. To find the amount of water in a swimming pool, find the volume by multiplying the length, by the width, by the depth. If the pool has a deep end and a shallow end, you can usually estimate the average depth as the same depth as the half-way mark. So a pool 50 meters by 25 meters by 2 meters deep (Olympic size)…

### How many gallons of water does it take to fill a swimming pool that is 4' x 24'?

That depends on how DEEP the pool is. The information provided only permits calculation of the AREA of the pool, not the volume and gallons are units of volume not area. To give you some idea though - here are the gallons for different depths: To fill the pool to a depth of 2 ft would require 1436 gallons To fill the pool to a depth of 3 ft would require 2154 gallons To fill…

### How many gallons of water does it take to fill a 24-foot by 4-foot swimming pool?

The basic formula to figure water volume or gallons of water for a specific size say 20 x 40 are as follows 20 x 40 = 800 x average depth(say 5') = 4000 x 7.5(gallons per cubic foot) = 30,000 In answer to your question you did not give enough information. Is it 24ft diameter? If so the formula is radius squared x 3.14 x 4(average depth) x 7.5 Or 12 squared(144) x 3.14(452.16) x…

### How many gallons of water will it take to fill a 14x42 pool?

You need to know the average depth of the pool. the depth of the deep end plus the depth of the shallow end divided by 2 will give an average. The formula for estimating the gallons of water is in a pool is; length times width times average depth times the multiplier 7.5 for a rectangle pool; 6.7 for a oval or free form pool. with this formula a rectangle pool 14X42 6 feet deep…
