# How Much Water Does A 13×33 Pool Hold? [Answered!]

The amount of water a swimming pool holds is usually specified in gallons (3.785) or litres (0.26785). However, there is often a lot of confusion about how these measurements work, so let us explain. When you look up the number of gallons or litres that a pool holds in a reference book, you will often see a figure in a similar form to this one:

13 x 33 = 44 gallons = 572 litres

This is incorrect. The correct way to think about this measurement is to imagine that each of the 13 swimming pools is holding exactly 33 gallons (in other words, there are 13 x 33 inches of water in each pool).

If you have exactly 44 gallons or 572 litres of water in your pool, you might be wondering how you are going to fit all of this in. The fact is that you can fit quite a bit of water in a swimming pool. For example, a 13-foot-by-33-foot pool can hold up to 144 gallons (576 litres) of water.

What might surprise you is that even bigger pools with the same dimensions can hold more water. A 15-foot-by-38-foot pool can hold 168 gallons (684 litres) of water. This is because all swimming pools are not created equal – some are much deeper than others. As you might expect, the deeper the pool, the more it can hold.

## Why Are Pools Measured In Gallons?

Pools used to be measured in pints (16 fl oz), quarts (4 pints) or liters (1.8 quarts). These units were generally used for measuring liquid volumes. For example, a pint of liquor was often served in a shot glass. A quart was the amount of liquor that you would find in a standard drink or a six-pack of beer. A liter was the standard unit of measurement for a car tank of gas.

When the US Army adopted swimming pools as a form of physical exercise, they decided to measure them in gallons. This made sense since gasoline was a commonly used fuel at the time and it was easier to measure by weight. However, it should be noted that the litre was the preferred unit of measurement in most parts of the world at the time, so many old school pools are still being referred to as ‘litres’.

## How Do Pools Differ From Tanks?

It is important to note that a pool is not the same thing as a tank. A pool is a contained space that you can access from any side. The fact that the water is usually contained means that you can more easily regulate the temperature as well. This is important because the human body can only withstand a limited amount of heat before its risks increase, especially in the elderly and very young. Even when the temperature is within the comfortable range, your body is still losing moisture and there is always the risk of your health taking a nosedive if you continue to overheat.

When you are dealing with large volumes of water, it is usually best to use a pool rather than a tank. With a pool, you can easily remove some of the water if necessary. You can also add more water if you run out, rather than having to return to your tank and refill it. The shape of a pool also makes it easier to fit more than one person in there. This is important if you have children with you or are taking a family vacation and want to use the pool more often than usual. In these scenarios, fitting more people in a pool than a tank might be desirable, however, this should be done carefully so as not to cause any accidents.

The shape of a pool also makes it easier to circulate the water if any objects are floating in it. This is important for fish tanks and boat storage, as buoyancy can cause all sorts of problems if there are any objects that are not designed to ride on the surface tension of the water.

## How Much Does It Cost To Maintain A Pool?

Pools are usually a relatively cheap form of outdoor recreation. This is mainly because they require very little in the way of maintenance. The water needs to be cleaned once or twice a week, and mild chemicals are usually sufficient for this task. Some pools even have an automatic pool cleaner that will take care of this process for you, so you can simply sit back and relax.

Of course, pools are not completely maintenance free. The chemicals that are used for cleaning the water can accumulate and cause some problems. However, this is very rare and most people have no problems with their pools once they are maintained properly. This is also partly due to the fact that pools are usually built in such a way that prohibits any invasive growth. This is important because many plants and animals don’t appreciate being crowded by humans, particularly when it comes to their habitat. While this might not always be the case, it is still a good idea to avoid upsetting the natural order of things whenever possible.

## Where Do Pools Come From?

Although most people assume that a swimming pool comes from the English language, this is not the case. Pools actually originate from the Roman Empire; specifically, the days of ancient Rome. It was customary for the upper classes to take their exercise in pools rather than the open air. In fact, many early Roman baths consisted of just a pool. This was because the Romans valued aquatic sports and exercise, so anything connected with the water was considered noble and fit for their social elite.

It was not until the 17th century that we see the first true swimming pools emerge. These were small affairs constructed by the sick and dying in their homes as a way to pass the time. It was not until the 18th century that we see public pools emerge as a safe form of recreation for the masses. However, it was not until later that yearros that we see the first municipal leisure pool in England open its doors to the general public.

What kind of shape should your pool be?

The shape of your pool is going to depend on you. If you are a competitive swimmer who uses your pool regularly, you might want to consider constructing a larger pool than usual. If you are just taking a leisurely dip now and then, you might want to consider a regular shape or oval shape for your pool. Another option is to have one that is completely circular, as this is the shape that most boats, cars and many other larger objects are designed to be in. The only drawback to this shape is that it is difficult to maneuver in particularly crowded conditions, such as when there are multiple lanes going past you at the same time. Another option is to have a pool that is completely square or rectangular (though this kind of shape is difficult to maintain due to the nature of gravity).

Whatever shape you choose, make sure that it is deep enough so that a child cannot accidentally fall in and drown. The depth of your pool is also going to depend on how long you plan on having it. For example, if you are planning on having the pool for the summer, you might want to go for either a really deep or long pool so that your children can continue to use it during school holidays. If you are only using the pool for an hour or two at a time, you can get by with a shallower pool. Shallow pools are also better for young children, as they can easily fall in and become tangled in the drain grate, especially when they push off with their feet while trying to swim. If this happens, gravity will inevitably pull them down, and this is usually the end of the story. It is also a good idea to cover your pool with a roof, especially if it is going to be outside in the sun. The shade provided by a roof can also protect you from overheating if you get too excited while swimming.

What kind of lighting do you prefer?

The lighting around your pool is going to depend on you. If you are a night swimmer who enjoys moonlight and the soft glow of the stars on the water, you might want to consider putting in some underwater lighting. This will not only add that touch of romance to your morning swim but will make the water much more visible, especially when you are snorkeling or scuba diving. If you are a daytime swimmer who enjoys having the sun shine down on you while you work out, you might want to put in some solar lighting or at least some mood lighting. If you have trouble getting in the mood for a workout in the morning, a little mood lighting can help ease you into that relaxed state of mind needed for swimming. However, if you are a late night swimmer who wants to get some peace and quiet, you might want to invest in some good quality noise-canceling headphones and listen to some smooth jams while you work out. This will help drown out the noise of birds chirping and cars humming by, making it a more relaxed and enjoyable experience overall!
