Convert acre-feet to other major units of volume. A unit used to measure volumes of water, typically for use in irrigation. One acre-foot is the amount of water that would cover an acre of land to a depth of 1 foot, = 43,560 cubic feet, approximately 325,851 U.S. gallons (approximately 1233.48 cubic meters).
Itâs a lot. Hereâs the math: one acre equals 43,560 square feet, and one cubic foot equals 7.481 gallons. So if one inch of rain is one twelfth of a foot, this means the volume of water that falls in an acre is 43,560 divided by twelve, or 3,630 cubic feet. That is equal to 27,156 gallons of water. Quite an abundance!
