Measure Pool Dimensions

To accurately calculate the gallons in your pool, you need to know its dimensions. This involves measuring the length, width, and average depth of your pool.

Step 1: Measure Length and Width

Using a measuring tape, measure the longest and widest parts of your pool. If your pool has an irregular shape, divide it into smaller rectangular or square sections and measure each section separately. Make sure to record these measurements in feet.

Step 2: Determine Average Depth

The average depth of your pool is the average of the deepest and shallowest points. To measure the deepest point, use a measuring stick or pole to reach the bottom of the pool at its deepest end. For the shallowest point, measure the depth at the steps or the shallow end of the pool. Add these two measurements together and divide by 2 to get the average depth.

Step 3: Calculate Surface Area

Once you have the length, width, and average depth, you can calculate the surface area of your pool. For a rectangular or square pool, simply multiply the length by the width. For an irregularly shaped pool, divide it into smaller rectangular or square sections and calculate the surface area of each section separately. Then, add the surface areas of all the sections together to get the total surface area.

With these measurements in hand, you can move on to the next step of calculating the volume of your pool, which will allow you to determine the number of gallons it holds.

Calculate Surface Area

To calculate the surface area of your pool, follow these steps:

  • Rectangular or Square Pool:

    Multiply the length by the width.

  • Oval Pool:

    Multiply the length by the width and then multiply that number by 0.785.

  • Round Pool:

    Multiply the radius (half the diameter) by itself and then multiply that number by 3.14.

  • Irregularly Shaped Pool:

    Divide the pool into smaller rectangular or square sections. Calculate the surface area of each section separately and then add the surface areas together.

Once you have calculated the surface area of your pool, you can move on to the next step of determining the average depth.

Determine Average Depth

To determine the average depth of your pool, follow these steps:

  • Measure Deepest and Shallowest Points:

    Using a measuring stick or pole, measure the deepest point in your pool. Then, measure the shallowest point, which is usually at the steps or the shallow end of the pool.

  • Add Measurements Together:

    Add the deepest and shallowest measurements together.

  • Divide by 2:

    Divide the sum of the two measurements by 2.

  • Average Depth:

    The result is the average depth of your pool.

Once you have determined the average depth of your pool, you can move on to the next step of calculating the volume.

Multiply Area by Depth

To calculate the volume of your pool, multiply the surface area by the average depth:

  • Formula:

    Volume = Surface Area × Average Depth

  • Units:

    Volume is measured in cubic feet.

  • Example:

    If your pool has a surface area of 500 square feet and an average depth of 5 feet, then the volume of your pool is 2,500 cubic feet.

  • Convert to Gallons:

    To convert cubic feet to gallons, multiply the volume in cubic feet by 7.48.

Once you have calculated the volume of your pool in gallons, you will know exactly how much water it holds.

Convert Cubic Feet to Gallons

Once you have calculated the volume of your pool in cubic feet, you need to convert it to gallons to determine the exact amount of water it holds.

There are two main methods for converting cubic feet to gallons:

  1. Multiply by 7.48:
    This is the most common method and it is very simple. Simply multiply the volume in cubic feet by 7.48 to get the volume in gallons.
  2. Use the Formula:
    You can also use the following formula to convert cubic feet to gallons:

    Gallons = Cubic Feet × 0.13368

    This formula is derived from the fact that there are 7.48 gallons in 1 cubic foot.

Example:

If your pool has a volume of 2,500 cubic feet, then you would multiply 2,500 by 7.48 to get 18,700 gallons. Alternatively, you could use the formula: 2,500 × 0.13368 = 18,700 gallons.

No matter which method you choose, the result will be the same: the number of gallons of water your pool holds.
