The U.S and Imperial measurement system
UK Imperial and the US system (a variation of the Imperial system). These were probably the most common due to the advancement in technology, growth of economy and population
The metric system came late into the implementation and nowadays in majority of the world metric system is being used. Since world has become global village and for ease of business people use standardize units to avoid any misunderstandings and hurdle in their business.
Still we see that British and America uses their own system in some cases as it has become part of their tradition and it’s hard for the people to change and shift to the new metric system which came quite late into the world.

How Many Ounces(oz) in a Quart?
To know how many oz in a quart, we would consider US and Imperial units. 1 U.S fluid quart is equal to 32 US fluid ounces and 1 US fluid once is equal to 0.026855 US dry quart, in imperial unit system 1 imperial quart is equal to 40 Imperial (Fl oz).
How many U.S liquid quart in U.S fluid ounces?
1 US liquid quart equal to one fourth of US liquid gallons. Now 2 U.S liquid pints are equal to 4 liquid cups which are then equal to almost 8 liquid gills (U.S). These 8 liquid gills are then equal to 32 fluid ounces.
And now we will discuss U.S dry quart
How many U.S dry quart equals to Imperial fluid ounce.
In U.S measurement system, one US dry quart equals to one quarter of dry gallon, or exactly 1.101lit or 38.758 imperial fluid ounces.
1 US dry quart equal to 1 by 32 bushels which are then equal to one eight of pecks that are 1⁄4 dry gallons
Remember all units are in U.S measurement system
Let’s come to Imperial quart measured in imperial measurement system:
How many imperial quarts in an ounce?
The imperial quart is same for both liquid and dry quart, is totally equal to one quarter of an imperial gallon and in litters is equal to 1.1 litters. So mathematically we have
1 imperial quart ≈ 38.430 US fluid ounces
Fun fact:
In Canadian (French), the imperial quart is called (pinte ).
Remember that, However on industrial level minimal difference in measurement level means a lot and it throws a huge impact on the quality and measurement of a product.

Frequently Asked Questions
Here are some frequently asked questions related to the topic of how many 16.9 oz in a gallon.
How do you calculate how many 16.9 oz water bottles equal a gallon?
As with all unitconversion problems, this is a matter of multiplying by fractions made of pairs of units that form special versions of multiplication by 1. In order to cancel out the units you have, and result in the units you want.
Here, the units we want are “water bottles“, and we know that one water bottle is equal to 16.9 oz. The units we are starting from are [U.S.] gallons, of which we have 1, and 1 gallon is equal to 128 oz. We proceed:
1 gal=1 gal×128 oz1 gal×1 water bottle16.9 oz≈7.57 water bottles1 gal=1 gal×128 oz1 gal×1 water bottle16.9 oz≈7.57 water bottles
This answer makes sense, since 16.9 ounces is approximately equal to 500 mL, or half a liter, a common size for commercial water bottles and there are about 3.79 liters in a gallon. Around 7.5 halfliter bottles would indeed add up to around 3.8 L. (16.9 oz is also 0.9 oz more than a [U.S.] pint, and there are 8 pints in one gallon.)
How many 16.9 water bottles do I need to drink for 100 ounces?
A little mental arithmetic will tell you “a little less than 6”, since 100/6 is 16.67.
100 ounces/16.9ounces = 5.9 ~ 6 bottles which is probably more than you need.
How many cups is 100 oz of water?
Conversion factor: There are 8 fluid ounces in 1 cup.
8 fluid ounces = 1 cup and
1 cup = 8 fluid ounces.
x cups = 100 ounces water / (8 ounces / cup)
Solving for x yields 12.5 cups
The ounces units cancel each other and the cup unit moves to the numerator (the top line in a fraction)
This could also be written like this:
x (unknown) cups (desired unit you wish the value in) = 100 [known quantity] ounces [unit of measure for known quantity)] * (1 cup / 8 ounces)
Conversion factors are employed to convert quantities expressed in one unit of measure to another unit by multiplying by them.
How many grams does 1 fluid oz of water weigh?
It depends a lot on the temperature, and curiously an fluid ounce of water weighs about 1.041 ounces avoir du pois !
This corresponds to about 29.6 grams.
How much does a fluid ounce of water weigh?
A fluid ounce of water weighs an ounce. That’s the very definition of a fluid ounce, it’s the volume of water that weighs an ounce.
Similarly a Litre of water weighs a Kilogram.
Conclusion
To answer how many 16.9 oz in a gallon is the simple, direct result to this calculation: according to U.S. standard is 7.5739645 bottles (take that as 7 and half bottles), and according to U.K standard is 9.46745562 bottles (consider roughly 9 and half bottles).
