(1 in) * 1 (mile^2) = 17,378,742.9 US gallons 17378742.9 US gallons PURE WATER ≈ 145,032,638.36815932 pounds ≈ 65,785.6982 tonnes Rain water is probably heavier than pure H2O .. but I really have no idea.
One inch of rain over one square foot is 1/12 cubic foot of water. A cubic foot of water weighs about 62.4 pounds. 1/12 of that is about 5.2 pounds.
One inch of rain over 100 acres of land would equal about 27.1 million gallons of water. This calculation is found by multiplying the acreage (100 acres) by the volume of water in one inch of rain (27,154 gallons per acre-inch).
It is estimated that one inch of rain falling on one acre of ground is equivalent to about 27,154 gallons of water.

One inch of rainfall on one acre is equivalent to 27,154 gallons of water. Therefore, four inches of rain on an acre would be equal to 108,616 gallons of water.

one inch of rain equals 3 cups of water (24 ounces) based on the area of a standard rain gauge.
1 sq ft = 144 sq inches 1 sq ft x 1 inch deep = 144 cubic inches / (231 cubic inches per gallon) = 0.6234 gallon (rounded)
one mile - 5280 feet one square mile = 5280 x 5280 = 27,878,400 sq ft since 1 inch = 1/12 ft, the total volume of rain is 27,878,400 / 12 = 2,323,200 cubic ft since 1 cu ft contains 7.48 gallons of water, then the totalfgallons is 2,323,200 x 7.48 = 17,377,536 gallons (wow,that is a lot of gallons)
12" x 12" x 1"= 144 cubic inches, which is equal to .623 gallons therefore a one thousand square foot roof receiving one inch of rain will catch 623 gallons.
