So that would mean that a 125 gallon tank , would in fact only be a 32
gallon tank.
working on the assumption that one American gallon is really only 1.2
litres or one quart Imperial, This gets more confusing the further we get
into it,,,
So how heavy is the fat lady that sits on the water bed, and what's the
water content.

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!
