There are 128 fluid ounces in one US gallon. This is the standard measurement used in the United States for liquid volume
. In contrast, the UK (Imperial) gallon contains 160 fluid ounces, which is a different measurement system
. So, if you are referring to the US gallon, the answer is:
- 1 US gallon = 128 fluid ounces.
If you need to convert other volumes:
- Half a gallon is 64 fluid ounces.
- A quarter gallon is 32 fluid ounces.
- Four 32-ounce containers make one gallon
This distinction is important depending on whether you are using the US or UK measurement system.
