and going down.....
gallon 128 oz
1/2 gallon 64 oz
quart 32 oz
pint 16 oz
1/2 pint 8 oz
gill 4 oz
1/2 gill 2 oz

gill like Jill.. but gill and half gill are almost never used.. except in old irish bars-- where 1/2 gill is a shot-- and gill is full double.. (as opposed to a standard double, which is just 3 oz.)--or at least that is the only place i have heard the word.

these being US measurement, not imperial ones..

does anyone know the scale for dry measure-- today portland cement is sold (US) in 90lb bags-- or half barrels. leading me to guess that 180 lbs is a full barrel-- but i presume that the barrel is really a volume measurement, and the 90lb is specific to portland cement--from someone, who in her time, has done way too much masonary work
