Answer Wiki. The short answer is eight -- there are eight U.S. pints in a U.S. gallon, and eight British pints in a British (or Imperial) gallon, which covers any realistic situation this might come up in.
In a US gallon... 128 ounces <br /><br /> Both US gallons and Imperial (UK) gallons contain 8 pints - but the US pint is 16 fluid ounces while the Imperial pint is 20 fluid ounces. <br /> So if you're working in Imperial gallons the answer is 160 fluid ounces.
