There are 8 pints (pt) in 1 gallon (gal). This means that 1 pint equals 1/8 gallon. So if you have a gallon of milk in your fridge, this would be equivalent to 8 pints of milk. Or, say you filled up your car with a half gallon of gas; this would be the same as 4 pints of gasoline (because 4 is half of 8).
