They say you need to drink 8 cups of water every day to stay hydrated and healthy. But what’s the size of each of these cups and how do you come to such a conclusion? Also, what does that mean in terms of either fluid ounces or liters? We will tell you.
Fluid Ounces vs Ounces
They might sound similar, but they are actually used for different purposes in reality. Fluid ounces and ounces are both standard units of measurement. But ounce is a unit of measure that is used to represent weight. It is typically used for ingredients like sugar, flour and such.
Interestingly, ounces can also be used to measure ingredients like yogurt or honey. That’s why you will notice this happen in notes for certain baking recipes. When it says ounces instead of cups, it means that they are talking about its weight. This is done because measuring some ingredients by weight with the help of a scale is more accurate.
Fluid ounces, on the other hand, is a unit of measurement that is used for volume. This means you use it to understand the amount of space a certain item takes. It is typically used for liquids like milk or water.
When you see fluid ounces in a recipe, you should take out a measuring cup to get the most accurate measurement of the liquid.
How Many Water Bottles of 16.9 FL Oz Each Is a Liter
To find out how many liters 16.9 fluid ounces is, multiply 16.9 by the number of liters one fluid ounce is to get the total volume. To compute the result, we may use a simple proportion:
1 fluid ounce = 0.02295 liters
16.9 fluid ounces = volume (in liters)
So, by cross multiplication:
Volume in liters x 1 fluid ounce = 16.9 fluid ounces x 0.02295 liters
16.9 fl oz = 0.499 liters
You can rest assured knowing that in the US, two water bottles that are 16.9 fluid ounces each make for a liter.
And if you are looking at 6-ounce cups, in the US, each of these cups has a capacity of 8 fluid ounces. And each liter is about 33.814 fluid ounces or 1,000 ml. So, about 4.22 such cups make a liter.
Since each cup is eight fluid ounces, you are told to drink eight cups of water every day. If you are looking at water bottles that are disposable, you should consume about three or four such bottles on a daily basis.

And if you want to know how many eight-ounce cups make 16.9 ounces is, you just need to divide that number by 8.
Since one cup is eight ounces, two such cups make 16 ounces.
