Most people don’t know how much water is in their pool. That’s because it’s not something we think about on a daily basis. However, when you’re trying to figure out how much chlorine or other chemicals to add, it’s important to know the volume of water in your pool.
The short answer is that 1 gallon of water weighs 8.34 pounds, so a standard residential pool holding 20,000 gallons of water would weigh approximately 167,000 pounds. But there are other factors to consider when estimating the weight of your pool water.
If you have a standard in-ground swimming pool, it likely holds between 15,000 and 20,000 gallons of water. An above ground pool typically holds 3,000 to 5,000 gallons. Of course, these are just estimates – the only way to know for sure how much water your pool holds is to measure it.
Why do you need to know how much water your pool holds? Well, there are a few reasons. First of all, it can help you determine how much chlorine or other chemicals you need to add in order to keep the water clean and safe.
It can also help you estimate how long it will take to fill up your pool if you need to top it off (or empty it out completely).
Knowing the gallon capacity of your pool can also be helpful in case of an emergency – if there’s a major leak or spill, you’ll want to know approximately how much water needs to be replaced. Plus, if you live in an area with drought conditions or water restrictions, knowing your pool’s gallonage can help you make sure that you’re not using more than your allotment.
So grab a tape measure and calculate the length x width x depth of your swimming pool. Once you have those numbers, multiply them together and then divide by 7.5 (this will give you the number of cubic feet). Finally, multiply that number by 7.48 (this converts cubic feet into gallons).
And there you have it!
How Many Gallons is My Round Pool
If you have a round pool, you probably want to know how many gallons of water it can hold. After all, knowing the capacity of your pool is important for both maintaining the proper water level and ensuring that you have enough chlorine or other chemicals on hand to treat the entire volume of water.
So, how many gallons is my round pool?
The answer depends on the size of your pool. A standard 24-foot diameter above-ground pool holds 11,935 gallons while a 27-foot diameter model holds 16,500 gallons. In-ground pools vary in size even more than above-ground pools so their capacities can range anywhere from 5,000 to over 20,000 gallons.
To calculate the specific gallonage of your round pool, simply use this formula: Multiply the average depth of your pool by 3.14 (pi) and then multiply that number by the square footage of your pool’s surface area. This will give you an accurate measurement of just how many gallons are in your round pool!

How Many Gallons of Water are in a 18X36 Pool?
If you have ever wondered how much water is in your pool, you are not alone. Many people ask this question, but the answer may surprise you. Depending on the size and depth of your pool, the amount of water it holds will vary.
For example, a standard 18×36 pool holds approximately 22,710 gallons of water.
How Many Gallons is My Pool 24 Round?
Assuming you have a standard 24′ round above-ground pool, it holds approximately 5,455 gallons of water.
How Many Gallons is My 18Ft Round Pool?
If you have an 18ft round pool, it holds approximately 9,720 gallons of water.
How Many Gallons is a 15 Foot by 52 Inch Pool?
Assuming you are talking about a rectangular pool that is 15 feet wide and 52 inches deep, the volume of the pool would be 7,800 gallons. To calculate this, you would multiply the length (15 feet), width (52 inches), and depth (4 feet) to get the cubic footage of the pool. Then, you would divide that number by 7.48 (gallons in a cubic foot) to get the total gallon capacity of the pool.

Conclusion
If you’re like most people, you probably don’t know how many gallons of water your pool holds. And even if you did know, you might not be sure how to calculate it. Luckily, there’s a simple formula that can help.
To calculate the volume of a rectangular pool, simply multiply the length by the width by the depth. For example, if your pool is 20 feet long, 10 feet wide, and 5 feet deep, it would hold 1,000 gallons of water (20 x 10 x 5 = 1,000).
If your pool is round or oval-shaped, things are a bit more complicated.
To calculate the volume of a round pool, you need to multiply the radius (half the diameter) by itself, then multiply that number by 3.14 (pi). So, if your pool has a radius of 10 feet (diameter of 20 feet), its volume would be 1,256 gallons (10 x 10 x 3.14 = 1,256).
In short:
Rectangular pools: Length x Width x Depth = Volume in Gallons
