Standard plastic water bottles tend to come in a size and capacity of 16.9 fluid ounces. You can buy such bottles at any local convenience store or mart. These are usually single-use bottles, but many bottles of other materials that you can reuse also come in this size.

If you happen to have a few such bottles or use a water bottle of this size to get your regular water intake, you might be wondering how many such water bottles tend to equal two liters of water.

Once you figure this out, it can also become easier for you to measure and determine whether or not you are drinking enough water every day. Take a look!

**How Many 16.9 Fl Oz Water Bottles Equals 2 Liters?**

You will need around 4 water bottles of 16.9 fluid ounces to equal 2 liters. Thus, if you happen to be traveling or are used to buying such water bottles to help you get through the day, make it a point to buy at least 4 such bottles for yourself.

If you have a single water bottle of 16.9 fluid ounces, you can simply refill it 4 times (or more) every day so that you can drink enough water on a daily basis.

You should note that this is a measurement done for the sake of simplicity so that you can have an easier time remembering how much water to drink on a daily basis. Even if you do not have this kind of water bottle, it can help to know these measurements so that you can form an estimation of your water intake.

For instance, if you have an 8-ounce cup that you are used to drinking water from, you can remember that slightly over two such cups will fill up a single 16.9-ounce bottle, which means that you should drink around 8 such cups of water regularly.

**Should You Drink 2 Liters of Water Every Day?**

Yes, it is important to drink 2 liters of water every day, although you should aim for around 3. Using a 16.9-ounce water bottle or any other equivalent measure can help you remember to drink enough water regularly.

Of course, the exact amount that you drink can depend on your age, your level of daily physical exercise, how much time you spend in the sun or traveling/commuting, what kind of climate you live in, whether or not you have certain health issues or even on whether you are pregnant or breastfeeding.

Make it a point to get the minimal water intake otherwise, you might end up getting dehydrated. Too little water, in the long run, can also result in chronic health issues.

**Summing Up**

Essentially, 4 water bottles of 16.9 fluid ounces equal 2 liters. Whether you use 4 separate bottles or a refill a single bottle 4 times every day is up to you, but make sure you get enough water intake on a daily basis to ensure proper body functioning.
