An American gallon is 1.2 UK (imperial) gallons, and 3.79 litres or 3.33 UK
(imperial) quart, not 1.2 litres or one imperial quart. So 125 US gallons is
104 UK gallons, not 32!

Of course, you meant to say that one Imperial gallon is 1.2 American gallon.
One American gallon is thus 0.832 Imperial gallon.
