How many ounces in a gallon is a very common measurement system used for a variety of different applications, most notably for cooking or baking.
Also, remember to keep in mind that the US fluid ounce is different than the UK imperial fluid ounce.
The US fluid ounce is 29.5735 mL while the UK (imperial) fluid ounce measures 28.4131 mL.
