Similarly, you may ask, how do I calculate gallons in my pool?

Length x width x depth x 7.5 = volume Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic feet. 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.

Variable Depths With A Drop

If, instead of a gradual slope down to the deep end, your pool has a definitive drop between the shallow and deep ends, the average depth will be different, even if the shallow end and deep end are still, for example, 3 feet and 9 feet, respectively.

It may be easier, in this case, to treat the shallow and deep ends as separate pools. This will allow you to apply the volume of each section using the constant depth formula.

Once you have the volumes of both parts, simply add them together to determine the volume for the whole pool.

How To Calculate The Volume Of A Circular Pool

You can calculate the volume of a circular swimming pool by multiplying 3.14 times the radius in feet times the radius in feet times the average depth in feet times 7.48. Thus, the formula is:

volume = r2 × average depth × 7.48

The first part of this formula determines the area, and multiplying by the depth finds the volume. Multiplying by 7.48 finds the gallons of water per ft3 of water.

Olympic Swimming Pool Volume

To calculate the Olympic swimming pool volume, you need to know its dimensions. The length of the pool is 50 m, width 25 m, and the depth varies: 2.0 m is the minimum, but 3.0 m is the recommended depth. If you’re not familiar with those metric units, check out this length converter to convert easily the pool size to US or imperial units.

Olympic-size swimming pool contains 2,500,000 L of water, assuming a nominal depth of 2 m. It’s around 550,000 imp gal and 660,000 US gal – if you don’t believe us, you can check it with our volume converter tool, where you’ll find other volume units as well. Try to calculate the Olympic swimming pool volume for a recommended depth of 3 meters – or use the pool calculator to get the answer in the blink of an eye.

The Actual Formula And Gallons For 15×30 Pool

How many gallons of water does my pool hold ...

Assume you have found:

  • Width is 30
  • Average depth is 4

Also, assume you have a square, rectangle, or free form pool. You can compute the number of gallons it would hold as follows:

L x W x AD x M = Volume in Gallons

15 x 30 x 4 x 7.5 = 13,500 Gallons;;

Now assume you have an oval pool:

L x W X AD X M = Volume in Gallons;

15 x 30 x 4 x 5.9 = 10,620 Gallons;

You can also compute the volume of a circular pool as follows:

How Does The Pool Volume Calculator Work

The pool water calculator is a tool similar to the volume calculator; it also uses also the formulas from the square footage calculator.

Finding the volume of a pool is a simple matter of getting the area of the surface of the pool and then multiplying that by the average depth.

  • Start by entering the pool size .
  • Then add its depth at the two endpoints.
  • If there is both a shallow and a deep end, enter the shallow depth in the first field and the deepest point in the second. Otherwise, enter two identical values.
  • If the depth of your pool changes drastically instead of gradually, you may want to consider dividing it in half, with a separate pool calculator measurement for each part .

You could go one step further and, knowing the density of water , work out how much the water in such a pool would weight.

Pool Volume Calculation Examples

Example 1: Rectangular Pool. Let us say you need to fill a swimming pool with a simple rectangular shape such as a semi-olympic size with a length of 25 meters and width of 12.5 meters . If it’s depth is 2 meters all across, how much water do we need to fill it up?

Answer: This is a simple volume of a box calculation. The formula is Volume = Width &middot Height · Depth. In our case that’s 25m x 12.5m x 2m = 25m x 25m2 = 625m3 so we need six hundred twenty five cubic meters of water.

Example 2: L-shaped pool. A slightly more complex shape would be a swimming pool with an L-shape. If the left-side outer edge of the L has a length of 25 yards, the bottom of the L has a length of 15 yards and the right-side of the L has a length of 5 yards, and the top side has a length of 10 yards how do we find the total pool volume in cubic yards if we also know the depth is 2.5 yards?

Answer: First we split the L into two rectangular boxes, one with sides of 25 yards and 10 yards, and another with 15-10 = 5 and 5 yards. We calculate the two volumes separately: volume 1 is 25yd x 10yd x 2.5yd = 625 cu yd and volume 2 is 5yd x 5yd x 2.5yd = 62.5 cu yd. Then we simply sum the two parts of the pool: 625yd3 + 62.5yd3 = 687.5yd3.

Formulas Behind Pool Calculator

So you no longer need to worry “how many gallons is my pool?”, simply apply one of the formulas:

  • Rectangular / square pool
  • volume = length * width * / 2

    The first two agents is, of course, the formula for the area of the rectangle.

  • Oval / circle pool
  • volume = * / 2

    The first part of the equation comes from a standard area of an ellipsis formula: A = * a * b, where a, b are the distances between the center and the ellipse’s vertex, lying on the horizontal and vertical axes. In our case, we have the length and width values that are the doubled distances a and b, so in the final formula, we need to divide the surface area of an oval by 4.

    You are wondering why we average the depths / 2? Have a look at the pictures:

  • Here you have the standard rectangular pool. l stands for the length of the pool, w for width, d1 is depth on one end of the pool and d2 is the depth on the other end.
  • Let’s take the right trapezoidal side of the pool. “Cut” the triangle, with one apex in the midpoint of the side, as in the picture.
  • Flip and move it to the other side to form a rectangle. The edge of the new shape is the average of two sides, so / 2.
  • The area of such a rectangle is then length * / 2. Multiply it by the third dimension – the width – and you’ll get the final formula for rectangular pool volume:

    • volume = length * width * / 2
