There will always be 64 ounces in a half gallon. This is because there are 128 ounces per gallon. So, when you divide that in half, there is 64. Now that you know, write it down somewhere so you won’t forget. But, consider committing the conversion to memory.
While it’s always good to be able to look up the answer to questions of conversion, it’s best to remember these on your own. Not only will you be able to increase your brainpower with memory recall, you won’t always have to use the internet to help you with such things.
Memorizing Conversions
When you know off the top of your head how to convert measurements, it can provide for quicker calculations so you can continue with whatever it is you’re doing. So, always remember there are 128 ounces in a gallon regardless if its milk, paint, distilled water, vinegar or any other type of fluid.
Practical Problem-Solving
This means that gallons and ounces are a standard metric for liquids. Therefore, you can employ a simple equation every time you want to find out how many ounces you need from an entire gallon.
Example #1
Let’s say you have a large recipe for soup requiring 2 gallons of chicken broth. They usually don’t sell chicken broth in gallons, but they do offer it in 32-ounce cartons. You know there are 128 ounces in a single gallon.
So, two gallons of broth will equal a total of 256 ounces (128 + 128 = 256). If you divide 32 by 256, you will need eight cartons of chicken broth.
Example #2
As another example, let’s say you’ve already made a massive amount of apple cider you want to portion it out as gifts to friends and family. You know you have a total of 600 ounces but you want to put it into ½ gallons.
Since we know there are 128 ounces in a gallon, you can divide 600 by 128. This comes out to 4.6875 whole gallons. But, you want to know the number of half gallons. You can approach this one of two ways. Either you can change the equation or double 4.6875; the result will be the same regardless of the method.
600 ÷ 64 = 9.375
4.6875 + 4.6875 = 9.375
You can give nine half gallons of apple cider and still have ⅜ of a gallon left.
