An international acre is 4840 square yards or 6,212,640 square inches.
An imperial gallon is 277.14 cubic inches.
6,212,640 divided by 277.14 = 22,610 gallons approximately.
A US liquid gallon is 231 cu inches hence 1 acre inch = 27,154.3 US gallons (rounded)
1 acre-inch = 27,154.285 gallons [US, liquid]
1 acre-foot equates to 325,851.429 US gallons.
27,154 gallons for every inch deep
325,900 gallons.
1 acre-inch is 27,154.2857 US gallons.
Two acre-feet equates to 651,700 gallons.

Well, you know there are 43,560 square feet in an acre, and you know there are 12 inches to a foot. The next clue you need is a conversion factor from volume in gallons to the units of area, which in this case is inches; so, there are 231 cubic inches to a gallon. You now have all the information you need to algebraically determine the number of gallons in an acre inch.
There are far too many variables to say. The answer to this will be relaitive to your location, and you would need to take some measurements in your local area. The best way to calculate this would be to take a sample (say 1 foot square) and multiply your results by the number of square feet in one acre. A suggested means would be to use a rain gauge with a 1 foot square funnel, to measure total rain fallen on the area. then you would need to asertain the drop size. I would use a sheet of tissue paper, weigh it, then allow it to be hit by a single drop of average size, and then re-weigh. 1 gram will equal 1 millilitre, and thus you can work out how many drops by dividing your total water in your sample area. You may want to use a normal rain gauge in addition to this in order to get an acurate idea of when you acheive a 1 inch rainfall.
according to the USGS, 1" of rain peracre = 27,154 gallons; so 1" of rain on 100 acres would be 2,715,400 gallons
12.62 acre-inch contains 342,687.09 US gallons. (1 acre-inch is 27,154.3 gallons)
It depends on the depth of the water. Assuming the water in one inch deep, there would be about 13,577 gallons of water in the half acre.
1/16 acre-inch is about 1,697 US gallons.

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.
Six acre-feet of water is about 1,955,109 US gallons.
One acre-foot is about 325,851 US gallons.
I'm assuming you mean acre feet of water. If that is the case, then there are 325,850.58 gallons in one acre foot of water or 4,887,758.7 gallons of water in 15 acre feet of water.
1,135 acre-feet of water equates to 369,841,371 US gallons.
1 inch * 1 acre = 102.790153 m3 1 US gallon = 0.00378541178 cubic meter 102.790153/0.00378541178= 27 154.2849 So 27 154 gallons
22 acre-feet equates to 7,169,000 gallons of water.
