    So my town got 6.5 inches of rain today in 9 hours. I'd like to figure out how many gallons of water fell on a town of 13.25 square miles. Can anyone tell me how to figure this out? Thanks.

    I think a gallon is about 231 cubic inches. If that's correct, it's pretty easy from there (assuming uniform rainfall over the entire area)

    Those rains today were something, Larry. Still, whenever I hear about heavy rainfall, I think of the storms back in 1996 that dumped 17 inches on the western suburbs in 24 hours. One of my friends in Oswego had their home washed off their foundation during the resulting flooding.

    OK this is What I found


    A one inch storm Dumps 27,152 gallons of water on one acre of land. Now Multiply that by 6.5 and you get 162,912 gallons per acre. Now if my memory is correct there are 640 acres in a Square mile so Multiply 162,912 and 640 and you get 104,263,680 gallons in One Square Mile now take that and multiply it by 13 and 1,355,427,840 gallons.


    TOTAL Rain In Gallons= 1,355,427,840.00 WOW

    13.25 sq mi x 5280^2ft /sq mi x 144sq. in/sq. ft x 6.5 in rain / 231 cu. in/gal = 1.496 billion US gallons.

    That's 231 cu. in per US gallon, not imperial gallon.

    Also, did you know that a US gallon is actually 133.23 fl. oz, and not 128, like the milk jug? I did not. But, a US pint is still 16 fl. oz.
