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.
This is calculated by knowing that 1 acre is 6272640 square inches, and one inch deep gives you 6272640 inches cubed.
1 US gallon is 231 inches cubed, giving us exactly 27154.2857. (6272640/231)
22687
108,600 gallons.
according to the USGS, 1" of rain peracre = 27,154 gallons; so 1" of rain on 100 acres would be 2,715,400 gallons
None - an inch is a distance, a gallon is a volume. They are not directly linked.
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.
It can vary a lot - a common figure would be about half an inch of rain, but you could have an inch of water with very wet snow.
27,150 gallons.
An inch of rain implies water one inch deep per surface area. An inch of rain equals 5.61 gallons per yard. An inch of rain equals 27,150 gallons per acre.
108,600 gallons.
1 acre = 43,560 square feet1 inch = 1/12 footVolume = 43,560 x 1/12 = 3,630 cubic feet = 27,154.3 gallons (rounded)
1,496.104 gallons

First you need to figure out the volume of one inch of water covering one acre. 1 acre = 4840 sq yards = 4840 * 3 * 3 sq ft = 4840 * 3 * 3 * 12 * 12 sq in ==> 1 acre = 6,272,640 sq in So, the total volume of water is 6,272,640 * 1 cu in One gallon is about 231 cu in, so the amount of rain in gallons is 6,272,640 / 231 = 27,154 US gallons
according to the USGS, 1" of rain peracre = 27,154 gallons; so 1" of rain on 100 acres would be 2,715,400 gallons

Well, an acre is 43,560 sq. feet. One inch is 1/12 feet so one acre of water 1 inch deep is43560 1/12 = 3630 cubic feet of water.There are 231 cubic inches in an American gallon. A cubic foot is 12 inches by 12 inches by 12 inches and thus one cubic foot is 12 12 12 = 1728 cubic inchesso 3630 cubic feet is 3630 728 = 6272640 cubic inches. Thus the amount of water needed to cover one acre to a depth of 1 inch is 6272640/231 = 27154.3 gallons.
