It depends. How deep is the pool?
If this is a round pool that is 18 feet across and you fill it to 3 feet deep, the total volume would be about 5,735 gallons of water. Filling it to 4 feet deep will increase the volume to 7,646 gallons of water.
It depends on how deep it is. Multiply distance from center to edge in feet by itself then multiply that number by 3.14 then multiply that by how many feet deep it is and finally multiply that number by 7.48 and that number is your gallons.
8000 Gallons -- ANSWER -- For every foot of water in the pool there is 1,585 imperial gallons.
Cannot be answered without knowing the length, width and depth.
Impossible to answer without knowing how deep the pool is. When you know the depth (in feet), plug it into this equation:
18 x 18 x (depth) x 5.9 = # of gallons in the pool.
About 158.6 gallons per inch for an 18-foot diameter round pool.
If it is a round 18' in diameter and a constant 52" deep then the volume is 158.6 gallons per inch. 52 inches would then be 8247.2 gallons.

There are 6016.20 gallons of water for every 1 foot of heigth. Therefore, the total gallons is 24,065gallons. Hope this helps. Louis Daigle

How large is the pool? In ground or above ground? Shape? Above ground is easier to calculate. I have an oval above ground pool which is 18 x 38. It holds approx. 15,000 gallons. To get an accurate answer, you need to be far more specific.
We have a 24' foot round above ground with 13000.00 gallons of water and that only requires a 1 hp pump a 2 hp pump may be overkill and cost more to operate
