Acre foot

One acre-foot is the volume of water that stands over one acre of land if the water is one foot deep. Since there are 43,560 square feet in an acre and the total volume is area times depth, an acre-foot equals 43,560 cubic feet.

An acre of land with water one foot deep on it has a volume of water given by

Volume = (Area) (Average depth)

1 acre-foot = (43,560 ft²) (1 ft)

= (43,560 ft³)

Since there are roughly 7.5 gallons in a cubic foot

1 acre-foot = 326,700 gallons
