I am trying desperately to calculate how many acre feet I am using if I put 4 inches of water down on 4.4 acres?? Help!

1 ac-ft equals 43560 cubic feet. 1 acre equals 43560 square feet. If you multiply 4.4 acres by 43560 square feet you get 191664 square feet. If you convert 4 inches to feet you get 0.33 feet. You can then find out a volume by multiplying 0.33 feet by 191664 square feet giving you 63249.12 cubic feet. Since 1 acre-feet equals 43560 cubic feet you can then divide 63249.12 cubic feet by 43560 cubic feet and get 1.452 acre-feet. You can get the conversions from http://www.srh.noaa.gov/wgrfc/convert.html#volume

First use the Area conversion page to convert the base units to the same, such as inches.
