``````

fl oz = 3 x 128
fl oz = 384

``````So, there are 384 fluid ounces in 3 gallons.

Conversely, to convert from fluid ounces to gallons, use the following formula:
``````

gal = fl oz / 128

``````For instance, if you have 256 fluid ounces of liquid and want to know how many gallons that is, you would use the formula like this:
``````

gal = 256 / 128
gal = 2

``````Therefore, 256 fluid ounces is equivalent to 2 gallons.

## Examples

Here are a few examples of converting between gallons and fluid ounces using the formulas above:

- Convert 2.5 gallons to fluid ounces:
``````

fl oz = 2.5 x 128
fl oz = 320

``````Therefore, 2.5 gallons is equal to 320 fluid ounces.

- Convert 96 fluid ounces to gallons:
``````

gal = 96 / 128
gal = 0.75

``````Thus, 96 fluid ounces is equal to 0.75 gallons.

- Convert 1 gallon and 64 fluid ounces to fluid ounces:
``````

fl oz = (1 x 128) + 64
fl oz = 192
