One US liquid gallon of pure water at 3.98 deg C  weighs  8.345638 pounds Avoirdupois.
You may see a slightly different number elsewhere.  This one is based on the best measurement for the density of water that I can find; 1.000028  kilograms per liter.
Both the US pound and the US gallon are defined in terms of the respective metric units.
The British gallon is a different unit altogether and weighs 10 pounds.  You can see some information about gallons HERE
