1 acre = 43560 sq.feet. 1 foot deep water over an acre is 43560 cubic feet, which is 325851.4 gallons in 1 foot deep. If it is 1 inch deep (1/12 foot) then it is 27154.3 gallons in 1 inch deep.

1 US customary fluid ounce = 1.8046875 cubic inches1 sq foot 1 inch deep = 144 cubic inches = 79.792 fluid ounces (rounded)
About 2,360 pounds per square inch (psi) or 163 bar.
The question as posed is unanswerable. In order to compute the weight of an inch of water, one would have to know the volume, or area the one inch covers. (ie., a square foot of water one inch deep would weigh=X)
a 27 foot round by 52 inch deep pool holds 18,550 gallons of water
Pressure in seawater at 100 feet is 44 psi. Or, .44 pounds per square inch per 1 foot. For Fresh water, it is .43 psi per foot.
Exactly 5264.1669 gallons
