Depends on the size of the glass and (perversely) on the size of the gallon!. For some reason British gallons are larger than American gallons:
1 gallon(UK) = 1.2 gallons(US) (approx.)
However, let's assume that you are referring to British gallons, in which case
1 gallon(UK) = 8 pints(UK) = 4.546 Litres (approx.)
so, if you have a 1 pint glass then 8 glasses = 1 gallon(UK),
and if you have a 1/2 pint glass then 16 glasses = 1 gallon(UK),
and so forth.
There are 128 ounces in a gallon, so there would be 16 (128/8) 8 oz glasses in 1 gallon.
There are 128 ounces in one gallon of water. So, 16 eight-ounce glasses of water equal one gallon of water.
There are 64 ounces in half a gallon.
There are 64 ounces in half of a gallon. This can be determined because 1 cup equals 8 fluid ounces and 16 cups is equivalent to 1 gallon.
1/2 gallon = (64 fl oz) / (4 fl oz per serving) = 16 servings

There are 128 ounces in one gallon of water. So, 16 eight-ounce glasses of water equal one gallon of water.
There are approximately 10.7 twelve-ounce glasses in a gallon.
There are 64 ounces in half a gallon.

There are 128 fl ounces in a gallon, so you would divide 128 by two, because its a half gallon, then divide that number by two again because you are counting two ounce scoops as one. So, there are 32 two ounce scoops in a half gallon.
There are 64 ounces in half of a gallon. This can be determined because 1 cup equals 8 fluid ounces and 16 cups is equivalent to 1 gallon.
1 gallon equals 128 oz. There would be 12.8 units of 10 oz each.
16 glasses 1 gallon makes 128 ounces and 1 ounce is 0.0078 gallon in U.S measure. There are 8 ounces in a cup, 2 cups in a pint, 2 pints in a quart and 4 quarts in a gallon.
