May 10th, 2022|FAQ|

When you ask people the question how many fluid ounces are in a water bottle, you would always hear different answers. Some people believe that a water bottle may have a capacity of 17 fluid ounces, and others may argue that a typical water bottle should be of 25 oz. Again, still others may cling to the belief that a water bottle should have a large volume of 32 oz or even 64 fluid ounces. Why do people hold entirely different views on this question? And how many fluid ounces are in a water bottle? In this blog we will answers these question.

I. What Will Happen If You Drink 135 oz (4L) of Water a Day

In the United States, the typical disposable plastic water bottle is of 16.9 oz. So if you drink 135 oz water on a daily basis, you will have to refill a reusable stainless steel water bottle for 7 times or discard 8 plastic water bottles. Let’s put the environment-related issues aside and see what will happen if you drink such an amount of water per day.

feel tired hydration
  • Feeling bloated

Feeling bloated after drinking too much water in a second is quite common. If you swill water swiftly, you may suffer from sudden fullness and feel uncomfortable. Don’t worry, this feeling will soon disappear and you will be okay. However, when you feel bloated, your body is actually telling you that you should stop swilling any water at once as you are full, and next time you should avoid drinking excessive water in such a short period of time. It is recommended that you drink water slowly and frequently during the day in order to embrace a healthy hydration life.

  • Peeling frequently

Why do you pee so often? Have you ever thought about it? In fact, it is the stomach who is swollen and feels uncomfortable that turns to your body for help. Once the brain receives the MAY DAY, it will command your body excreting the retained excessive liquids through peeling or pooing. So if you consume 135 oz of water per day, you are expected to peel frequently in order to make the body function well. There are mainly two advantages of peeling. One is that you are forced to increase your activity volume, and the other is that your belly will flatten out with time going by!

  • Decreasing food intake

This benefit of drinking 135 oz of water on a daily basis may be ignored by many people. According to nutrition experts, drinking certain amounts of water before meal helps to dampen the digestive function by decreasing the secretion of a kind of hormone who is in charge of creating a craving for food. In other word, if you have adequate water intake, you will have a sense of fullness that enables you to eat less, thereby reducing calories.

  • Enhancing physical activity levels

Staying hydrated is conducive to making the body energized, why? One important reason is that water shoulders the responsibility of transporting glucose and oxygen, two vital ingredients to support your physical activities. So the more you consume, the better and stronger you will be. Besides, drinking adequate water also helps to lubricate muscles and joints eventually boosting your entire physical activity levels. There is one thing that deserves your extra attention: avoid drinking water only during the exercise. Nutrition experts point out that it is a must for people to drink before, during and after exercises so as to fully eliminate the occurrence of dehydration. And the pre- and after-exercise water consumption is exactly always underestimated by many people, which displays the same significance.

  • Cultivating a healthy hydration habit

And when it comes to water intake, you will be voluntarily called by the body to drink water, obviating the need of a clock for reminding. Believe it or not, you will be rewarded from this healthy hydration habit.

  • Protecting the environment

Here we return to the environment-related issues. As we have talked above, the typical single-use plastic water bottle is of 16.9 oz. And the required water consumption is 135 oz per day. So you will waste 8 plastic water bottles polluting the environment every day! But what about a reusable stainless steel water bottle / tumbler cup? You can get hydrated with such a eco-friendly water bottle and refill it 7 times to meet your daily hydration goal. The latter is absolutely much more environmental-friendly, economical and healthy.

V. How Many Fluid Ounces in a Tumbler Cup or Water Bottle?

As one of the discussion cores in today’s article, ounce, also written as oz, should be introduced first. Ounce is a unit of measurement that is often adopted to measure the volume of fluids & liquids and dry ingredients.

Value of ounce is different for different countries that hold their own systems of measurements. For instance, in the United States, 1 fluid oz is equal to 29.57 ml, whereas 1 fluid oz equals 28.413 ml in the United Kingdom. What’s more, the measurement for dry oz is also different. For example, 1 oz equals 437.5 grains and 28.349 grams. Here we offer you the American unit conversion from ounce to milliliter:

U.S. measurement system
1 fluid oz 29.57 ml
2 fluid oz 59.15 ml
3 fluid oz 88.72 ml
4 fluid oz 118.29 ml
5 fluid oz 147.85 ml

In the United States a typical bottle is of 16.9 oz, and this can be viewed as an answer.

VI. What Is a Gallon?

Now you have known what an ounce is, you should also understand what a gallon is. Gallon is another unit of measurement that is larger than ounce. Similar to ounce, gallon can be used to measure the volume of liquids and is variable according to different measurement systems. And this unit of measurement is adopted in water bottles when these bottles are incredibly big (usually over 128 oz).

There are main two measurement systems of gallon, namely, U.S. system and imperial measurement system (U.K. system). Here we provide you with the corresponding conversion charts.

U.S. measurement system
1 gallon 3.79 liters
3.79 liters 128 oz
1 gallon 128 oz
2 gallon 256 oz
3 gallon 384 oz
U.K. measurement system
1 gallon 4.54 liters
4.54 liters 160 fluid oz
1 gallon 160 fluid oz
2 gallon 320 fluid oz
3 gallon 480 fluid oz

In U.S. measurement system, If 1 bottle is of 16.9 oz, then liquids of 1 gallon can be held in 7.57 such bottles!

It is quite clear that there is a huge difference between gallon and oz in U.S. measurement system and in U.K. measurement system.

VII. Measurements, Physical Conditions, Drinking Habits

Measurements of reusable water bottles are variable, and so do people’s physical conditions and drinking habits. In general, an athlete requires way more water intake than an adult. It is virtually understandable as the former needs a larger water consumption to stay energized in case of dehydration. So if you ask a football player the question mentioned above, he or she must give you a big number. The same goes for people’s drinking habits. Those who regularly drink certain amounts of water will ask for more water consumption, and may even stay hydrated with a bottle of a larger capacity. In this way, these people can enjoy hydration while reducing the frequency of refilling.
