# How Many 16.9 Ounces Make A Gallon?

When measuring liquids, most people use the standard measurement of a gallon. This is not only used for drinking water, but also in baking and cooking. A gallon is always equal to eight pounds of liquid.

Unfortunately, this unit is changing soon due to international standards. By October 2019, the standard gallon will be set at ten pounds of liquid instead of eight pounds. This is due to a new definition for the kilogram that requires greater accuracy.

Because our weights and measures are linked, changing one requires changing them all to keep consistency across the world. The weird thing about this change is that gallons will not increase in size, but ounces will decrease!

This upcoming change will make it harder for those working in fields that rely heavily on gallons to do their work correctly.

## Four 8.4 ounce bottles of water make a gallon

Now let’s talk about how many 8.4 ounce bottles of water make a gallon. Most people would assume that four 8.4 ounce bottles of water make a gallon, but they would be wrong.

Water is a strange substance, and its density can change depending on where you get it from. Because of this, the standard measurement for a gallon of water is eight pounds of weight per square foot area in depth.

Because an 8.4 ounce bottle of water is thinner than one square foot in depth, it would not measure up to the standard gallon measurement. Because of this, the number eight was changed to four when deciding how many bottles make up a gallon.

I hope you enjoyed learning about how many 16.

## Four 16.9 ounce bottles of juice make a gallon

In America, a gallon is defined as four 16.9-ounce bottles of liquid. So, in a sense, a gallon is not a literal gallon.

This definition comes from the International System of Units, or SI units. In the SI system, a gallon is defined as exactly 3.785411784 liters.

That’s pretty precise, isn’t it? Well, it turns out that the Imperial Gallon (which America uses) is slightly less than that–3.768421 liters to be exact.

That tiny difference probably has something to do with why America chose the size of the gallon bottle that it did. It’s close to a whole number, so it’s easier to measure out liquids in it.

## Four 16.9 ounce bottles of soda make a gallon

In America, the standard gallon is defined as 128 ounces of liquid. This definition has been around for a while, so you can be sure it is correct.

Technically, a gallon can be defined as any volume containing 128 ounces of liquid. So technically, a gallon could be almost any size container.

However, in practice gallons are almost always a specific size: 3.785 liters. A liter is a pretty big unit of volume, so that explains why gallons are so big.

So how many 16.9 ounce bottles of soda make a gallon? The answer is 4! Pretty easy question for you if you have just one bottle, but what if you have an entire fridge full?

Well, let’s do the math: A regular sized bottle or can of soda contains 16.9 ounces of liquid. If you have 4 bottles in your fridge then you have 4 x 16.9 = 79.2 ounces of liquid in your fridge.

## Twelve 8.4 ounce bottles of juice make a gallon

We mentioned earlier that a bottle of water is 8.4 ounces, so how did the gallon of water idea start? No one is really sure, but many believe it has to do with the amount of water it takes to grow a gallon of wheat.

It would make sense that people would associate the amount of water needed to grow an entire plant with a gallon since that is how they measured things back then.

However, in today’s world, we know that a gallon is actually 128 ounces, which makes no sense when looking back at the wheat explanation. So, if you are ever thirsty and need a gallon of water, go for it! You are allowed to have more than eight cups of water per day, so this will not hurt you.

## Twelve 16.9 ounce water bottles make a gallon

In order to figure out how many 16.9 ounce water bottles make a gallon, you will need to divide the total number of ounces in a gallon by 12. You will then need to round up or down to the nearest whole number.

For example, let’s say there are 8 gallons in a tub full of water. You want to know how many 12-ounce bottles you need to fill it?

You would divide the number of gallons in the tub (8) by the number of ounces in a bottle (12) and get 0.75. You would then round down to the nearest whole number which is 0.7, so you would need 7 bottles to fill your tub!

Try it yourself and see if you get the same result.

## Twelve 16.9 ounce juice bottles make a gallon

We mentioned this already, but it is important to stress: you cannot technically make a gallon of anything with sixteen and nine ounce bottles. You would have to use twenty-four bottles to make a gallon, and that would not be efficient.

So, how many 16.9 ounce juice bottles make a gallon? Twelve! This is a quick and easy answer for you.

You can also do this with water bottles. One gallon of water is equal to four half-gallons, or eight one-quart bottles. So, twelve one-quart water bottles make a gallon of water!

Again, these answers are only correct because we use the same measurement for the container and what is contained within it. You could not do this with milk cartons, though. A gallon of milk is equal to four quarts, or eight two-quart containers.

## Twelve 16.9 ounce soda bottles make a gallon

Now let’s talk about how many 12-ounce soda bottles make a gallon. Most people would guess six, assuming everyone drinks the same amount.

However, since a gallon is 128 ounces, you would need six 12-ounce soda bottles that each contain 1 ounce of water to make a gallon.

That would not be enough soda for everyone, so most people would say twelve makes a gallon. Twelve 12-ounce sodas is one gallon!

So if you are at the beach and someone asks how many 16.9-ounce water bottles make a gallon, tell them twelve! Or tell them six, depending on how much water they want to bring back with them.

## Twenty-four 8.4 ounce juice boxes make a gallon

Now let’s talk about how many 16.9 ounce water bottles make a gallon. Technically, one 16.9 ounce water bottle does not make a gallon. But in reality, one bottle can be considered a full gallon.

One gallon of water is equal to approximately eight pounds. So one gallon of water weighs eight pounds, which is quite heavy!

So technically, one gallon of water is equal to eight pounds and one quart of water is equal to one pound. This makes sense when you think about how much water you need to pour out to get one gallon or how much weight it has.
