Measure the diameter, that is the distance from one side directly to the other side as you cross the center. Take that distance and divide it by two to get the radius. Then measure the height of the pool, i.e. how far it measures from top to bottom along the side. Apply the formula pie x radius squared x height. I.e. take the radius measurement and multiply it by itself (square it) and then multiply that number by 3.14 (pie) and then multiply that number by the height. Your final number will be the volume in whatever units you measured the height and radius, i.e. inches cubed or cubic inches if your radius and height were in inches. OR, if you don't want to do THAT, you will need two things. 1. $5 an hour 2. A mathematician Here's a somewhat simpler formula which uses the dimensions in feet and gives the answer in gallons: diameter X diameter X depth X 5.9 = volume in gallons This and formulas for other shapes can be found here: http://www.kingtechnology.com/infostation/info512.htm

up to six feet with a dish style bottom on round above ground pools.
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.
8,600 gallons.
I have a 12' above ground round pool that is fillable up to about 29 inches and it holds roughly about 1600 gallons so yours will probably hold more than 2000 gallons.
I used a sand base for our 20' round above ground pool. It's much easier to deal with after the pool is gone. Greener too.
Your round pool has a volume of 2463 cubic ft. The formula to achieve this is Pi * (radius squared) * depth of 4 ft. Converting this to U.S. Gallons comes to 18,425 gallons.
Pie times the radius squared
30 gallons
Due to the differences in engineering and the parts involved, there really is no way to convert an oval above ground pool into a round pool.
