    Could someone help me with the formula to find the cubic feet total amount of water to water a square ft at .5" of water. This would be helpful in calculation the relative cost to run an irrigation system for a given square ft area. I have formulas to figure it out once its designed, but would like to have it based on sq ft. to use as a rough estimate. I'm sure I'm just being dense, your help is apreciated.

    That's very simple. Half an inch of water on a one-square-foot area is 1/24 of a foot on said area, equalling 1/24 cu ft total water.

    It takes 27154 gals to cover an acre 1" deep. There are 7.6 gals per cu ft. Go for it Tiger.

    Hey, I'm not going to do the math for him. It's easy enough to convert from gal to cu ft. I think. Isn't it? Oh well, have fun. Acre inch is about 3500 cu ft.

    You can use google to make calculations as well. Try typing in your dimensions and what you want the results diplayed in, in a google search bar. Honestly, try it. Paste this sample in a google search bar:
    .5 inch * 50 feet * 100 feet in gallons
