To calculate how many cups is 16.9 oz, we have to just divide by 8, there are 8 oz in every cup. So to answer this question it is 2.1125 3 cups 1oz.
About 2 cups. 8 oz is 1 cup, and 8 + 8 would equal 16. So, I would figure about 2.
If we were to get 8 cups of water a day, we would have to drink 4 16.9 oz water bottles, if that is what we are referring to.
How many cups in a gallon?
The exact calculation of how many cups in a gallon is as:

1 US liquid gallon = 1 UK gallon = 16 cups

1 US dry gallon = 18.61 cups
One US fluid gallon and one UK (royal) gallon have similar change of 16 cups. The US dry gallon then again is changed over to 18.61 cups.
However, cups to dry gallons are not, at this point utilized in business settings since they are currently utilizing the unit of estimation called bushel for dry fixings. For this issue, what you have to recall is that there are 16 cups in a gallon.
What Is the Difference Between the Metric System and the Imperial System?
When Great Britain was not officially switched to the metric system in 1965, they had what was called the British Imperial System. The U.S. system of weights and measures is based upon it. The unit conversions between the two are notoriously difficult, mostly because fluid ounces are a measure of volume, not weight.
 Depending on where we are, either 20 or 16 fluid ounces equals one pint.
 Milk, for example, is about 23% denser than water, which weighs about 1 pound per 16 fl. oz., so a little bit over a pound.
 Even the Canadians got wise: the U.S., along with Liberia and Myanmar, are the only ones left clinging to things like imperial cups—which are just shy of a full metric cup.
When it comes to cooking, converting from pints can be tricky because stores commonly sell fresh produce by weight, not volume.
Volume Conversion for US Ounces to Cups
8 fluid ounces = 1 cup
Volume Conversions for US Cups to Pints
2 cups = 1 pint
How Many US Cups in a Gallon?
Gallons  Cups 

1 US fluid gallon  16 US cups 
1 US dry gallon  18.6 US cups 
1 Imperial gallon  18.18 metric cups

1 gallon of milk  16 cups 
1 gallon of coffee  20 cups of coffee beans 
½ gallon of water  8 cups 
½ gallon of milk  8 cups 
½ gallon of coffee  8 cups 
Summary
The gallon is a unit of measurement for liquid volume. A US liquid gallon measures 3.785 liters (rounded), whereas the imperial (UK) gallon measures 4.546 litres (rounded). That’s a significant difference  the imperial gallon is 20% larger than the US gallon.
How Many Cups in a Quart?

A quart (qt) is the same thing as 4 cups or 2 pints.1 Quart (US, liquid)** = **4 (US, liquid) cups. 1 Imperial quart = 0.25 gallon. Quart is unit of capacity in the Imperial measurement system and U.S. Customary systems of measurement. The UK quart is same for both the liquid and dry measurements.
1 US fluid quart is exactly equal to 946.352946 milliliters or roughly around 1 litter. 1 Imperial fluid quart equals 1.136 liter
How Many Cups in a Pint?
If we remember, 8 ounces = 1 cup, 2 cups = 1 pint (or 16 ounces = 1 pint).
There are generally 2 cups in 1 pint, however depending on the ingredient, this may change. For example, 1 pint of Blueberries = 2 cups = 12 ounces (dry), whereas 1 pint of sour cream or 1 pint of ice cream = 2 cups.
How Many Cups in a HalfPint?
½ Pint = 1 cup
Measurement Conversion Table:
1 US Gallon = 4 Quarts = 8 Pints = 128 ounces = 16 US cups
1 Quart = 2 Pints = 32 ounces = 4 US cups
1 Pint = 16 ounces = 2 US cups
Threefourths of a cup = 12 tablespoons
Half of a cup = 8 tablespoons 4 ounces
Third of a cup = 5 tablespoons and 1 teaspoon
Fourth of a cup = 4 tablespoons 2 ounces
Eighth of a cup = 2 tablespoons
1 tablespoon = .90 cubic inches
1 Quart = 2 Pints
1 Pint = 2 cups, 32 Ounces
1 ounce = 2 tablespoons
1 tablespoon = 3 teaspoons
How many Ounces in a cup of water?
How many ounces in a cup of water? The answer to this question is liquid measuring cups indicate that 1 cup of water has 8 fluid ounces. But what they really mean is 1 cup of liquid = 8 fluid ounces. For dry measurements, the rule changes. Because dry ingredients vary greatly in weight with each other, you can’t rely on the same conversion. For example, 1 cup of flour weighs 4.5 ounces, not 8 ounces. On the other hand, 1 cup of chocolate chips weighs a little over 6 ounces.
1 standard cup of UK has 9.607 US fluid ounces in it.
8 ounces = 1 cup and 16 cups = 1 gallon
16 ounces = 2 cups = 1 pint and 8 pints = 1 gallon
32 ounces = 4 cups = 1 quart and 4 quarts = 1 gallon
128 ounces = 16 cups = 1 gallon
33.8140226 ounces = 1 liter
1000 ml = 1 liter
3.7854118 liters = 1 gallon
Summary
US dry volumes are a different system than US liquid volumes. Confusingly, they are also named (dry) pints and (dry) quarts. Outside the US, dry ingredients are usually measured by weight.
