Gallons to Ounces Converter

Whenever there is a need to convert any unit of volume, converters are used to save time in manual calculations. Well, as we all know that Gallon is used into volume unit, which is used in the US (United States). Whenever any measuring unit has to be obtained by converting the gallon, the different measurement systems must be considered, while, the ounce unit is used for measuring both weight and volume. Therefore, when the volume of a gallon has to be converted into ounces, the value of an ounce (US Fluid) is used. Different calculations for different unit systems are complex for humans to remember. Therefore, you can use the gallons to ounces conversion tool to eliminate mistakes and get the correct converted value to save time and effort.

This gallon to oz converter is a free online tool that helps you convert a gallon's volume value into ounces and get the correct result. Suppose you want to convert another unit of volume, like a liter or a deciliter, or are looking for a way to convert a gallon into a liter or a liter into a deciliter. In that case, you can use the Deciliter to Liter Conversion and Gallon to Liter Conversion tools given on our site. Now, do you think about how many ounces are in a gallon?

How many ounces in a gallon?

Here is the answer to your question:-

1 Gallon (Gal) = 128 Ounces (Oz), vice versa
1 Ounce (Oz) = 1/128 Gallons (Gal)

When calculating the value of gallons from ounces in US customary units, these value conversion units are used. But do you know how many ounces are in a gallon in UK customary units? If not, then here is the answer

1 Gallon (gal) = 160 Ounces (oz), reverse
1 Ounce (oz) = 1/160 Gallons (gal)

How do you convert a gallon into ounces?

No calculation can be done in mathematics without a formula, so whenever a gallon has to be converted into oz, the conversion formula is used, but a gallon in the US and imperial systems. Therefore, whenever we have to convert gallon to ounce, for a US gallon, we multiply the digit of gallon by 128 because there are 128 fluid ounces in one US liquid gallon. If we have to convert the gallon through the imperial system, especially taking UK customary units, then we multiply the gallon by 160 because there are 160 fluid ounces in one imperial gallon. Let us understand this language through formulas and examples.

Fluid ounce (oz) = Gallon (U.S) × 128
Fluid ounce (oz) = Gallon (Imperial) × 160

For example:

Q. How many oz in 8 gallons?

Sol.

By using the US gallon method,
1 US gallon has 128 fluid ounces
Then 8 gallons will have fluid ounces:

Fluid ounce (oz) = Gallon (U.S.) × 128

Fluid ounce = 8 × 128
Fluid ounce = 1024 oz

If ounces are to be obtained in the Imperial system

If one imperial gallon has 160 fluid ounces

Then eight imperial gallons will have ounces =
Fluid ounce (oz) = Gallon (imperial) × 160
Fluid ounce (oz) = 8 × 160
Fluid ounce (oz) = 1280 oz

Now, you must have understood that converting gallons to ounces is easy, but it is worth remembering which system to use to convert to ounces. So you can get out of this estimation by using a gallon-to-ounce calculator and simplify calculations with any other digit.
