If the metric system was applied in the US (as it is the official unit system), this question would be excessively easy to answer because 1 liter of water = 1 kilogram of water (it's not even an approximation...).
Now 1 US liquid gallon = 3.785 411 8 liter
1 kilogram = 2.204 622 622 pound
So 1 gallon of water = 3.785 411 8 x 2.204 622 622 = 8.3554044878 pounds
Which makes 16 gallons of water = 133.686471 pounds or about 134 pounds.
But it only works for water. If you want to convert volume to mass, then you have to know the volumic mass of your item. Or in the case of a kitchen staple like flour or sugar, you could remember that:
1 cup of flour is 4 oz
1 cup of sugar is 8 oz

It depends whether you are using US or imperial (UK) gallons
In UK
A pint of water weighs a pound and a quarter
A gallon weighs 8 x this
So 16 gallons weighs 8 x 16 x 1 1/4 pounds (in UK)
=160 pounds
In the US
a pint's a pound the world around
so 16 US gallons weighs 8 x 16 x 1 pounds
=128 pounds

1 pint = 1 pound, so 1 gallon = 8 pounds
16 gallon = 128 pounds
In order to convert a volume to a mass you need to know the density of the substance. For water in non-metric units, remembering that a pint (2 cups) of water weighs a pound is pretty easy. But then you have to remember that a gallon is 8 pints....

How Much Water Weigh

16galW x 8.320lbW/1galW = 133 lb You use the density.
It would be good to memorize the conversion factor of 8.320 lb/gal for water. This is because if you're ever given the specific gravity of another liquid, or the density of the other liquid in g/mL or g/cu cm, you can find the density of the other liquid in lb/gal by multiplying by 8.320.

At 32 degrees F density od water is
62.293 lb/cubic foot
and 1 cubic foot = 7.480 519 481 gallon [US, liquid]
so density times voluem = weight
W=(62.293lb/ft^3) (1 ft^3 / 7.480gal) x (16 gal)
W=133lb

A U.S. gallon weights 8.328 lbs at 60 degrees F. You can do the rest of the math.

I believe its 1lb/1 pint. Not sure how many pints are in gallon.
