# Round Pool Volume Calculator With Volume Charts

Calculating the volume of your round swimming pool shouldn’t involve you trying to remember high school math. That’s why we’ve put together a round pool volume calculator so you can easily work our how many gallons (or litres) your pool holds.

## Round Pool Volume Calculator (Gallons or Litres)

To calculate how much water is in your round pool:

Step 1) Select the units: gallons or litres
Step 2) Enter your pool’s measurements in feet or meters

## About the Round Pool Volume Calculator

The round pool volume calculator is an online pool volume calculator tool that is specifically designed to calculate the volume of round swimming pools in gallons or litres.

You’ll need to measure your pool diameter and the average depth and enter these in the calculator. Then you can let the calculator do the rest.

In addition to the calculator, we’ve also included pool volume charts for a quick reference. And the formula for to work out the capacity of your round pool and how to measure your round pool, just in case you fancy exercising your brain.

## Round Pool Volume Charts

Another way for you to work out the volume of your round pool is to use the quick reference pool volume charts below. I’ve included common circular pool sizes and depths. Many pools such as Intex, Summer Ways and Bestway all have similar volumes and sizes.

To use the volume tables, just find your pool’s diameter (width across the pool) and the depth. Keep in mind that these are approximate values.

The charts below are suitable for circular shaped swimming pools. Pools like Intex Easyset.

## Measurements to Work Out Round Pool Capacity

Working out the capacity of your circle shape pool is easy. You only need two measurements:

2. Average Depth

Diameter is the “width” of the pool from edge to edge, whilst passing through the center. Whilst the radius is half the diameter.

You’ll need the radius to calculate the volume of your circular shaped pool.

### Average Depth

Most round pools have a constant depth, unlike rectangular or oval shaped pools which can have a deep end and a shallow end. This makes it even easier. All you need to do is measure the high of the wall of your pool. For a more precise measurement, you can reduce the measurement by about a foot or 30 cm, since most of the time the pool won’t be filled to the brim.

## How Do I Calculate the Volume of a Round Pool?

There are two ways to calculate the volume of a round pool: use a formula or using a round pool volume calculator.

We already have you covered if you’re going to use the calculator. But if you want to do a bit of math, here is how.

### Formula to Calculate Round Pool Volume

Here’s the formula to find your round pool’s volume:

V = πr² x D

V = Volume
π = pi (3.14)
D = Depth

### Calculating a Round Pool Volume in Gallons

To use the above formula for calculating your round pool’s volume in gallons, you’ll simply substitute your pool’s depth and radius for the letters above in the formula. You’ll need your measurements in feet.

Now you have the volume in cubic feet. Next, you’ll need to convert it to Gallons.

#### Converting Cubic Feet to Gallons

To convert the volume of your round pool’s water in cubic feet to gallons, multiply it be the conversion factor of 7.48.

### Calculating a Round Pool Volume in Litres

To use the above formula for calculating your round pool’s volume in litres, substitute your pool’s depth and radius for the letters above in the formula. Use meters for your measurements.

Now you have the volume in cubic meters. Next, you’ll need to convert it to Litres.

#### Converting Cubic Meters to Litres

To convert the volume of your circular pool’s water from cubic meters to litres, multiply it be the conversion factor of 1000.

## What Can You Use the Round Pool Volume Calculator For?

The pool volume calculator for round and circular pools can be used for a range of practical applications. These include:

### 1. Estimating Round Pool Water Filling Requirements

The calculator can be used to estimate how much water you need to fill up your pool. Just input the dimensions of your round pool and let the calculator work out the volume of water you require to fill your pool. It will calculate the requirements in both litres and gallons.

### 2. Calculating Chemical Treatments

Before adding any chemicals to your round pool, you’ll need to know the pool’s capacity. This is a crucial step. If you get this wrong, then you can easily add too much or not enough chemicals to the water.

Whether you need to adjust the pH, add chlorine or apply other chemicals to the water, you’ll need to know your circular pool’s volume first.

### 3. Equipment Selection

When choosing new equipment for your round pool, like a pump or a filter, it’s important to know the pool’s volume. A more powerful pump is required for pools with more water in them, where as a smaller pump can be used for smaller pools.

## What’s the Standard Depth of a Round Pool?

Whilst there is no standard depth of a round pool there is an average or standard range of depths that are common. On average, round or circle shaped pools are around 3 feet (0.9 meters) to 4.5 feet (1.4 meters) in depth.

This depth is deep enough for swimming whilst allowing relaxation and game playing.
