A note sent in by a visitor about the definition of gallons: "He says that the imperial gallon is not defined in cubic inches and the litre definition is merely a conversion factor. 1 standard gallon is the volume of 10lb of water, hence its division 160 fl oz. Your definition as a strange number of cubic inches and litres makes the unit seem rather odd when it is in fact a good round number of normal units."
