The chart below shows conversion between gallons and fluid ounces.
Ainat [17]
<h3>Answer:  768</h3>

======================================================

Explanation:

To go from gallons to fluid ounces (abbreviation fl oz), we multiply by 128

For example, 2 gallons becomes 2*128 = 256 fl oz as shown in the table.

Another example: 3 gallons = 3*128 = 384 fl oz.

Therefore, 6 gallons would be 6*128 = <u>768</u> fl oz.

To go in reverse, from fl oz to gallons, we divide by 128.
